86 topics, each explained 7 units

SSC JE is the Staff Selection Commission's examination for Junior Engineer posts in fourteen central organisations — CPWD, Military Engineer Services, the Border Roads Organization, the Central Water Commission, DGQA-Naval, NTRO and others — at Group 'B', Level-6 of the pay matrix (₹35,400–1,12,400). The 2026 notice, published on 02.09.2026, puts 1748 tentative vacancies on the table and keeps applications open until 22.09.2026. Selection is two computer-based papers on the engineering part you opt for. The one thing worth fixing in your head before you plan a single week: Paper-I is only qualifying — it decides who reaches Paper-II — and the final merit is drawn from normalised Paper-II marks alone.

Exam Pattern

Paper	Subject	Questions / Marks	Duration	Negative marking
Paper-I (computer-based)	General Intelligence and Reasoning — compulsory	50 / 50	2 hours (2 hours 40 minutes for candidates eligible for a scribe)	0.25 marks per wrong answer
Paper-I (computer-based)	General Awareness — compulsory	50 / 50	2 hours (2 hours 40 minutes for candidates eligible for a scribe)	0.25 marks per wrong answer
Paper-I (computer-based)	The one part you opted for: Part-A Civil & Structural, Part-B Electrical, Part-C Mechanical, or Part-G Telecommunication for JE (Telecom) (Part-D, Part-E or Part-F for Scientific Assistant, IMD)	100 / 100	2 hours (2 hours 40 minutes for candidates eligible for a scribe)	0.25 marks per wrong answer
Paper-II (computer-based)	The same part you opted for, and nothing else	100 / 300	2 hours (2 hours 40 minutes for candidates eligible for a scribe)	1 mark per wrong answer

Tentative schedule in the notice: Paper-I in October/November 2026, Paper-II in December 2026. The online application window is 02.09.2026 to 22.09.2026 (fee until 23.09.2026, correction window 28.09.2026–30.09.2026), and the notice states that any change in the schedule will be told to candidates only through the Commission's website. Negative marking is not the same in the two papers — 0.25 marks are deducted for each wrong answer in Paper-I but a full 1 mark in Paper-II — so a guess that is worth taking in Paper-I is often not worth taking in Paper-II. One thing that misleads candidates who planned early: SSC's own Tentative Calendar of Examinations for the Year 2026-2027 had listed this as the 'Junior Engineer (Civil, Mechanical & Electrical) Examination, 2026', advertised in March 2026 with Paper-I in May–June 2026. This notice, published on 02.09.2026, replaces those entries — the dates above are the ones that now apply — and it also carries a fourth part, Part-G Telecommunication, for the JE (Telecom) post in the Department of Telecommunications, which the calendar's title does not name.

Full Syllabus

1 Paper-I — General Intelligence & Reasoning (50 questions, 50 marks) 50 Q

Compulsory for every candidate. The notice says the test includes both verbal and non-verbal questions, and lists the items below as what it may cover (§14.2.1).

What the syllabus lists	What it means and how to prepare
analogies	Two things are related in some way; you find the pair that is related the same way. Work word, number and figure analogies together — the underlying move is identical.
similarities	Picking what a set of items share. In the exam this usually arrives as odd-one-out, so practise naming the shared property out loud before you look at the options.
differences	The same skill from the other side — what breaks the pattern. Speed here comes from checking one property at a time instead of staring at the whole set.
space visualization	Turning, folding and viewing a shape from another side, in your head. Paper folding, cube folding and mirror images are the recurring forms; a few real paper cut-outs teach this faster than a hundred solved examples.
problem-solving	Mixed puzzles with no fixed formula — seating, ranking, blood relations, direction sense. Draw the situation instead of holding it in your head; almost every mistake here is a memory mistake.
analysis	Breaking a statement or a data set into its parts before judging it. Newly named in the 2026 notice, and it usually shows up as statement-and-conclusion or data-sufficiency items.
judgment	Choosing the sounder of two defensible options. Practise by writing one line on why the option you rejected is weaker — that habit is what the section actually tests.
decision-making	Applying a given set of conditions to a case and saying what follows. Read the conditions twice and the case once; the trap is always a condition you skimmed.
visual memory	Holding a figure in mind and finding it hidden inside a larger one. Embedded figures and figure-completion are the standard forms; ten minutes a day is enough.
discrimination	Telling near-identical items apart. New in the 2026 list, and it rewards a slow first look rather than a fast one.
observation	Noticing the detail that decides the answer — a changed shading, an extra dot, a reversed arrow. Non-verbal series questions live or die on this.
relationship concepts	Family and blood-relation chains, including the 'pointing at a photograph' phrasing. Draw the family tree with symbols for male and female every single time.
arithmetical reasoning	Short word problems where the arithmetic is easy and the set-up is the question — ages, averages, ratios, coded arithmetic.
verbal and figure classification	Grouping words or shapes by a rule you have to discover. If two options both fit, your rule is too loose — tighten it until exactly one survives.
arithmetical number series	Find the rule, then the missing term. Check differences first, then ratios, then squares and cubes, then alternate terms — in that order, every time.
abstract ideas and symbols and their relationships	Symbol-and-notation questions where nothing means what it normally means. Rewrite the given code as a small dictionary before you touch the options.
arithmetical computations	Plain calculation under time pressure. Tables to 20, squares to 30 and the common percentage-to-fraction conversions save more marks here than any technique.
other analytical functions	The notice's own catch-all, so treat the previous years' papers as the real syllabus for this line rather than guessing what else could come.

2 Paper-I — General Awareness (50 questions, 50 marks) 50 Q

Compulsory for every candidate. The notice also sets a ceiling on how deep it will go: no question here is meant to need specialist study of any one subject (§14.2.2).

What the syllabus lists	What it means and how to prepare
the environment around the candidate and its application to society	The section's own framing sentence: awareness of the world you live in, not textbook recall. Reading one newspaper properly beats three static GK books.
current events	Last twelve months, with the six months before the exam weighted heaviest. Keep one page per month rather than a growing file you will never revise.
everyday observations and experience in their scientific aspect	Everyday science — why a pressure cooker works, why iron rusts. Expect application, not definitions.
India and its neighbouring countries — History	Ancient, medieval and modern India, with the freedom struggle carrying the most questions. Fix the timeline first; names attach to a timeline far better than to a list.
Culture	Classical dance and music forms, festivals, monuments, UNESCO sites. Almost entirely a matching exercise, so learn it in tables.
Geography	Physical features, rivers, soils, climate and the map of India, plus its neighbours. Do it with an atlas open — every question is a place.
Economic Scene	Budget headings, banking and RBI basics, major schemes and the terms used in the news. Definitions plus the current number, nothing deeper.
General Polity	The Constitution's structure, fundamental rights and duties, Parliament, judiciary and important amendments. The Articles that recur are few; learn those cold.
Scientific Research	India's space, defence and atomic-energy programmes, ISRO and DRDO missions, and recent discoveries in the news. Keep it to what was reported this year.

3 Part-A — General Engineering (Civil & Structural), Paper-I and Paper-II

For the post of JE (Civil). Paper-I carries 100 questions and 100 marks from this part; Paper-II carries 100 questions and 300 marks from the same part. §14.2.3 lists these subjects by name for Paper-I; §14.3.1 prints the detail below for Paper-II. The engineering standard is approximately Diploma level.

What the syllabus lists	What it means and how to prepare
Engineering Mechanics — system of forces, free-body diagrams, equilibrium equations; internal forces in structures; friction and its applications; centre of mass, moment of inertia	The grammar every later chapter is written in. Practise resolving a force system and drawing a clean free-body diagram until it is automatic — marks lost here get lost again in Solid Mechanics and Structural Analysis.
Solid Mechanics — bending moment and shear force in statically determinate beams; simple stress and strain relationships; simple bending theory, flexural and shear stresses; uniform torsion; buckling of columns; combined and direct bending stresses	Sketching bending-moment and shear-force diagrams is the highest-return skill in this part — it feeds Structural Analysis, Concrete Structures and Steel Structures. Learn the standard beam cases by heart, then apply the stress formulae to them.
Structural Analysis — statically determinate and indeterminate structures; method of superposition; analysis of trusses, arches, beams, cables and frames; slope deflection and moment distribution method; influence lines	Start by classifying the structure — determinate or not — because that single decision picks the method. Truss analysis by the method of joints and sections is the most asked single item.
Construction Materials — bricks, stones, timber, steel, cement, aggregates, plastics, polymers, glass, concrete, concrete mix design, testing of concrete	Mostly recall, so it is the cheapest scoring block in the Civil paper. Build one table of material, standard test and acceptance value and revise only that table.
Construction Management — types of construction projects; project planning and network analysis: PERT and CPM	Small chapter, predictable questions: critical path, float, and the difference between the probabilistic PERT and the deterministic CPM. Solve five networks and it is done.
Estimating, Costing and Valuation — fundamentals of estimating, cost estimates for works, rate analysis, valuation, detailed estimates	This is the JE's daily job, so the paper asks it every year. Practise centre-line and long-wall/short-wall quantity take-offs until both give you the same number.
Concrete Structures — working stress and limit state design concepts; design of beams, slabs and columns; foundations and retaining walls; bond and development length	The IS 456:2000 table is given to you on screen, so the marks are in knowing which table to open and why — not in memorising its numbers.
Steel Structures — working stress and limit state design concepts; bolted connections, welds; design of tension members, compression members and beams; plastic analysis of beams and frames	Connection design and slenderness ratio carry most of the questions. Keep the failure modes of a bolted joint on one card — the paper asks you to name them.
Surveying — principles of surveying; errors and their adjustment; maps, scale and coordinate systems; chain and compass survey, plane table surveying, levelling and trigonometric levelling; traversing and triangulation survey; total station; tacheometric surveying, theodolite surveying, advanced surveying equipment	A wide chapter with narrow questions: levelling arithmetic (rise and fall versus height of instrument), bearing conversions, and one numerical on tacheometry. Total station and advanced equipment are asked as definitions only.
Soil Mechanics — three-phase system and phase relationships, index properties; Unified and Indian standard soil classification; permeability and one-dimensional flow; seepage, flow nets, uplift pressure, piping, capillarity, seepage force; effective stress and the quicksand condition; compaction of soils; one-dimensional consolidation and time rate of consolidation; shear strength, Mohr's circle, effective and total shear strength parameters, stress-strain characteristics of clays and sands	The phase relationships at the top generate a third of the numericals in this chapter, so get void ratio, porosity, water content and unit weights fluent before anything else.
Fluid Mechanics — properties of fluids, fluid statics; continuity, momentum and energy equations and their applications; laminar and turbulent flow; flow in pipes, pipe networks; concept of lift and drag	Bernoulli's equation with its corrections is the single most used tool here. Practise it with real pipe problems rather than as a formula to recite.
Hydraulics — forces on immersed bodies; flow measurement in channels and pipes; channel hydraulics: energy-depth relationships, specific energy, critical flow, hydraulic jump, uniform flow	The specific-energy curve explains critical flow and the hydraulic jump together; draw it once properly and both stop being separate topics.
Hydrology — hydrologic cycle, precipitation, evaporation, evapo-transpiration, watershed, infiltration; unit hydrographs and hydrograph analysis; reservoir capacity; flood estimation and routing; groundwater hydrology, steady-state well hydraulics and aquifers; application of Darcy's Law	The unit hydrograph is the one concept the paper returns to. Understand what 'unit' means in it and the numericals become mechanical.
Irrigation — types of irrigation systems and methods; crop water requirements: duty, delta and evapo-transpiration; gravity dams and spillways; lined and unlined canals; cross drainage structures	Duty, delta and base period are related by one small formula that shows up almost every year — derive it once instead of memorising three versions of it.
Water and Wastewater Quality and Treatment — physical, chemical and biological water quality parameters; water quality index; unit processes and operations; water requirement; water distribution system; drinking water treatment	Learn the treatment train in order — screening, coagulation, sedimentation, filtration, disinfection — because most questions ask what a named unit does or where it sits.
Sewerage system design — quantity of domestic wastewater; primary and secondary treatment; effluent discharge standards; sludge disposal; reuse of treated sewage for different applications	Sewage is the mirror image of water supply, so revise the two together and only the discharge standards need separate memory.
Air Pollution — types of pollutants, their sources and impacts; air pollution control; air quality standards; the Air Quality Index and its limits	Recall-heavy and current-affairs-friendly. The AQI bands and the national standards for the common pollutants are the two things actually asked.
Municipal Solid Wastes — characteristics, generation, collection and transportation of solid wastes; engineered systems for solid waste management: reuse and recycling, energy recovery, treatment and disposal	Short and almost entirely factual. Sanitary landfill design and composting versus incineration cover most of what gets asked.
Transportation Infrastructure — geometric design of highways: cross-sectional elements, sight distances, horizontal and vertical alignments; geometric design of railway track: speed and cant	Sight-distance formulae and superelevation are the reliable numericals; railway cant is one formula that is worth having by heart.
Highway Pavements — highway materials, their desirable properties and tests; desirable properties of bituminous paving mixes; design factors for flexible and rigid pavements; design of flexible and rigid pavement using IRC codes	Keep flexible and rigid pavements in two columns of one table — load transfer, failure mode, design input — because the paper's favourite question is the contrast.
Traffic Engineering — traffic studies on flow and speed, peak hour factor, accident study, fundamental relationships; traffic signs; signal design by Webster's method; types of intersections; highway capacity	Webster's signal design is a set procedure — do it three times end to end and it becomes a guaranteed mark. Traffic signs are pure recall.

4 Part-B — General Engineering (Electrical), Paper-I and Paper-II

For the post of JE (Electrical), and for JE (Electrical & Mechanical) through the electrical route. Paper-I carries 100 questions and 100 marks from this part; Paper-II carries 100 questions and 300 marks from the same part (§14.2.3.1 and §14.3.2). The engineering standard is approximately Diploma level.

What the syllabus lists	What it means and how to prepare
Fundamentals of Electrical Engineering — electrical circuit elements: resistors, capacitors, inductors and batteries and the factors affecting their values and performance; voltage, current, power, energy and flux and their units	Units and their relationships decide a surprising number of easy marks. Write the SI unit next to every formula you learn and you will stop losing them.
Network Solution Methods — KCL, KVL, node analysis and mesh analysis	New in the 2026 Paper-II list alongside network theorems. Pick one method per circuit type — nodes for parallel-heavy circuits, meshes for series-heavy ones — and stop switching mid-problem.
Network Theorems — Thevenin's, Norton's, superposition and maximum power transfer theorems	Thevenin and Norton are the same answer in two shapes; convert between them until it takes no thought. Maximum power transfer is usually a one-line question.
Magnetic Circuits — flux, reluctance, self and mutual inductance, magnetomotive force, magnetic circuits	Treat a magnetic circuit exactly like a resistive one — MMF is the voltage, flux the current, reluctance the resistance — and this chapter costs you almost no new effort.
A.C. Fundamentals — RMS and average values of alternating waves; simple series and parallel A.C. circuits; resonance; balanced three-phase circuits; star-delta transformation; complex power and power factor in AC circuits	RMS values, the resonance condition and the √3 relations of a three-phase system are asked every single year. They are cheap marks — do not leave them for revision week.
Measurement and Measuring Instruments — measurement of voltage, current, power and power factor; classification of instruments and types of errors; galvanometer, ammeter, voltmeter, wattmeter, Wheatstone bridge, Kelvin's double bridge, energy meter, megger; constructional features and calibration of the single-phase electronic energy meter; CT and PT and their uses	For each instrument keep three facts — what it measures, what range, what error. Kelvin's double bridge and the megger are the two most often confused with each other.
Electrical Machines — single-phase and three-phase transformers; DC machines, their types, characteristics, losses, efficiency and applications; AC machines: single-phase and three-phase induction motors, starting, speed control methods, electrical braking and torque-speed characteristics	The largest single block of the electrical paper. Transformer tests (open circuit and short circuit) and induction-motor slip and torque-slip curves are the recurring numericals.
Special Electric Machines and Synchronous Generators — fractional motors, servomotors; armature reaction; parallel operation of generators; synchronisation	Mostly conceptual. Know the conditions that must be met before two alternators can be put in parallel — that is the standard question.
Generation, Transmission and Distribution — types of power stations; load factor, demand factor and diversity factor; power factor and its improvement; types of transmission and distribution lines; transmission line parameters; corona effect and Ferranti effect; circuit breakers; protection of generators and transformers; coaxial cables, their ratings and efficiency	The three factors — load, demand, diversity — are defined so similarly that most marks are lost by mixing them up. Write all three definitions on one line and compare them.
Estimation & Costing — estimation of lighting schemes; electric installation of machines and the relevant IE Rules; earthing practices and IE Rules	Site work turned into questions. The IE Rules on earthing are asked as straight recall, so read the rule numbers once rather than reasoning them out.
Utilization of Electrical Energy — illumination, electric heating, electric welding, electroplating, electric traction and drives	Illumination carries the numericals (lumen, lux, the inverse-square law); traction and welding are asked as applications.
Basic Electronics — P-N junction diodes, rectifiers and wave-shapers, clipping, clamping; BJT and FET transistors and their characteristics; amplifiers; oscillators	Ripple factor and efficiency of the standard rectifier circuits are the dependable numericals; transistor configurations are asked as a comparison table.
Power Electronics — static V-I characteristics of the thyristor; firing and gating circuits for the thyristor; DC to DC conversion: buck, boost and buck-boost converters; single-phase half-controlled, full-controlled and midpoint-controlled rectifiers	The converter output formulae in terms of duty ratio are three short expressions that answer most of the questions in this chapter.

5 Part-C — General Engineering (Mechanical), Paper-I and Paper-II

For the post of JE (Mechanical), and for JE (Electrical & Mechanical) through the mechanical route. Paper-I carries 100 questions and 100 marks from this part; Paper-II carries 100 questions and 300 marks from the same part (§14.2.3.2 and §14.3.3). Because the mechanical and electrical papers are different, the notice states their scores are normalised against each other for the final merit (§13.18).

What the syllabus lists	What it means and how to prepare
Engineering Mechanics — free body diagrams and equilibrium, resultant of forces, Lami's theorem, laws of friction, sliding and rolling friction, centroid of geometrical plane figures, centre of gravity of simple solids	Lami's theorem solves three-force problems in one line, and centroid values for standard shapes are worth memorising rather than deriving under time pressure.
Strength of Materials — simple stress and strain, types of beams, shear force and bending moment, simple bending and deflection of beams, torsion of shafts, thin cylindrical shells	The same BMD and SFD skill the Civil paper needs. Standard cantilever and simply-supported results memorised now save you a derivation in the exam hall.
Theory of Machines — cams and followers; belt, chain, rope and gear drives; gear trains; flywheels and governors; balancing and vibration; brakes; dynamometers; clutches; bearings	Gear trains and governors carry the numericals; the rest is mechanism identification. Draw each mechanism once — a picture holds far better than a paragraph.
Machine Design — types of loads and stresses; creep and fatigue; theories of failure; design of cotter joint, knuckle joint, lever and crank; antifriction bearings; design of sunk key, shaft, couplings, spur gear, power screw and springs; design of screw fasteners, bolted joints and welded joints	Theories of failure are asked as 'which theory suits which material' far more often than as a calculation. Learn that mapping first.
Materials Science and Engineering — crystal structure and bonds; iron-carbon phase diagram; heat treatment of steel; types of cast iron and steels; major non-ferrous alloys such as aluminium alloys, nickel-copper alloys and bearing alloys; material properties and testing; non-destructive testing; corrosion	The iron-carbon diagram alone answers a large share of this chapter — learn to read its regions and the heat-treatment questions answer themselves.
Thermal Engineering — sources of energy; laws of thermodynamics; thermal power plant; heat pump, heat engine and refrigerator; steam generators; steam turbines, impulse and reaction; cooling tower; internal combustion engines: Otto, Diesel and dual cycles with P-V and T-s diagrams; types of IC engines; air compressor; refrigeration and air conditioning	The biggest scoring block in the mechanical paper. Draw the P-V and T-s diagram of every cycle from memory — nearly every numerical starts from one of those two pictures.
Thermal Engineering (continued) — gas turbine and jet propulsion; properties of steam; steam generators; steam nozzle; steam turbine; heat transfer by conduction, convection and radiation; heat exchangers	The notice prints this as a second paragraph under Thermal Engineering rather than a new heading, and it is where the steam-table questions live — the table itself is given to you on screen.
Fluid Mechanics and Hydraulic Machinery — properties of fluid; fluid flow; fluid flow through pipes; continuity equation; impact of jets on plates and curved vanes; hydraulic turbine and power plant; centrifugal and reciprocating pumps	Turbine and pump specific speed, and the difference between centrifugal and reciprocating pumps, are asked almost every year.
Industrial Engineering — site selection and plant layout; work study and work measurement; production planning and control; statistical quality control; inventory control	The EOQ formula and the control-chart basics are the two reliable questions. Everything else here is definitions.
Manufacturing Engineering — pattern making, moulding, casting; metal forming; gas, arc and resistance welding; types of lathe and lathe operations; broaching machine; drilling; milling; gear making; grinding and finishing; press working	Process-identification questions dominate: given a job, which process makes it. Keep one table of process, product and typical defect.
Metrology and Measurement — precision, accuracy, sensitivity, repeatability, range, calibration; linear and angular measurement; comparators; form and surface finish measurement; CMM; limits, fits and tolerances; interchangeability	Limits and fits is the one topic here with a guaranteed numerical — practise reading a hole-basis and a shaft-basis fit both ways.
Advanced Manufacturing Processes — jigs and fixtures; CNC milling machine and machining centre; PLC; special purpose machines; non-traditional machining processes such as EDM, ECM, AJM, LBM and EBM; fundamentals of CAD/CAM; industrial robot configurations and FMS	Almost entirely recall: which non-traditional process suits which material and why. One comparison table covers this whole row.

6 Part-G — Telecommunication, only for the post of JE (Telecom)

New in this cycle and easy to miss: the Department of Telecommunications recruits JE (Telecom) through the same examination, with its own Part-G in both papers (§14.2.3.6 and §14.3.7). It is conducted in a separate batch from the other parts, a separate merit list is drawn for it, and the notice sets its standard at approximately graduation level, not Diploma level.

What the syllabus lists	What it means and how to prepare
Engineering Mathematics — linear algebra (vector space, basis, linear dependence and independence, matrix algebra, eigenvalues and eigenvectors, rank, null space, solution of linear equations, least squares solution); calculus (mean value theorems, integral calculus, definite and improper integrals, partial derivatives, maxima and minima, multiple integrals, line, surface and volume integrals, Taylor series); differential equations (first-order linear and nonlinear, higher-order linear, Cauchy's and Euler's equations, variation of parameters, partial differential equations, variable separable method, initial and boundary value problems); vector analysis (gradient, divergence and curl, Gauss's, Green's and Stokes' theorems); complex analysis (analytic functions, Cauchy's integral theorem and formula, sequences, series, convergence tests, Taylor and Laurent series, residue theorem); probability and statistics	Note the standard: for Part-G the notice sets questions at graduation level, not diploma level. This is the widest row on the page — start from linear algebra and calculus, because signals, control and communications all lean on them.
Network Analysis — circuit analysis: node and mesh analysis, superposition, Thevenin's, Norton's and Tellegen's theorems; sinusoidal steady state analysis: phasors, complex power, maximum power transfer theorem; transient, time and frequency-domain analysis of linear RL, RC and RLC circuits, solution of network equations using the Laplace transform; linear two-port network parameters Z, Y, h and ABCD, reciprocity and symmetry conditions, cascade, series and parallel interconnections, wye-delta transformation	Two-port parameters are the part most candidates skip and the part most often asked. Learn the conversion table between Z, Y, h and ABCD.
Signals and Systems — continuous-time signals: Fourier series, Fourier transform, Laplace transform and their properties, sampling theorem, convolution and applications, inverse transforms, transformation of signals; discrete-time signals: DTFT, DFT, z-transform and their properties and inverse transform, discrete-time processing of continuous-time signals; LTI systems: definition and properties, causality, stability, impulse response, convolution, poles and zeroes, frequency response, group delay, phase delay, LTI systems in terms of differential and difference equations and in terms of transforms	The sampling theorem and convolution properties give the quickest marks. Causality and stability read off the pole positions — learn that reading once and it serves control systems too.
Electronic Devices — energy bands in intrinsic and extrinsic semiconductors, equilibrium carrier concentration, direct and indirect band-gap semiconductors; carrier transport: diffusion current, drift current, mobility and resistivity, generation and recombination of carriers, Poisson and continuity equations; P-N junction, Zener diode, BJT, MOS capacitor, MOSFET and their circuit configurations; LED, photo diode and solar cell	Drift versus diffusion is the distinction the paper keeps testing. Get that clear before moving to device characteristics.
Analog Circuits — diode circuits: clipping, clamping and rectifiers; BJT and MOSFET amplifiers: biasing, AC coupling, small-signal analysis, frequency response, current mirrors and differential amplifiers; op-amp circuits: amplifiers, summers, differentiators, integrators, active filters, Schmitt triggers and oscillators	Op-amp configurations are the highest-yield rows: derive the gain of the inverting and non-inverting forms once and every later circuit is a variation.
Digital Circuits — number representations: binary, integer and floating-point; combinatorial circuits: Boolean algebra, minimisation using Boolean identities and the Karnaugh map, logic gates and their static CMOS implementations, arithmetic circuits, code converters, multiplexers, demultiplexers, decoders, encoders, half adder, full adder, look-ahead carry adder, multiplier, comparator; sequential circuits: latches and flip-flops, counters, shift registers, finite state machines, propagation delay, setup and hold time, critical path delay, conversion of flip-flops; data converters: sample and hold circuits, ADCs and DACs; semiconductor memories: ROM, SRAM, DRAM; computer organization: machine instructions and addressing modes, ALU, data-path and control unit, instruction pipelining	Karnaugh-map minimisation and flip-flop conversion are the two things asked as actual work rather than recall — practise them on paper, not by reading.
Control Systems — basic control system components; feedback and feedforward principle; transfer function and Laplace transform; block diagram representation and reduction principle; signal flow graph and Mason's gain formula; transient and steady-state analysis of LTI systems, static error coefficients and generalized error coefficients; frequency response; Routh-Hurwitz criterion and Nyquist stability criteria; Bode plots, gain margin and phase margin, and root locus plots; lag, lead and lag-lead compensation, minimum phase system; state variable model and solution of state equations of LTI systems, controllability and observability	Routh-Hurwitz is a mechanical procedure that reliably earns a mark; Bode and root locus need sketching practice, not reading.
Analog Communications — random processes: autocorrelation and power spectral density and their properties, wide and strict sense stationary, ergodicity, filtering of random signals through LTI systems, low-pass equivalent of band-pass signals; noise: properties of white noise, thermal noise, shot noise, noise figure, noise equivalent bandwidth; amplitude modulation and demodulation, envelope detector, angle modulation and demodulation, efficiency of AM, spectra of AM, DSB-SC modulation and demodulation, Costas receiver, SSB-SC modulation and demodulation, FM modulation and demodulation, NBFM and WBFM, Carson's rule of bandwidth, frequency discriminator, phase locked loop, noise analysis for DSB-SC and SSB-SC modulation, superheterodyne receivers	Carson's rule and AM power efficiency are two formulae that come back every year. Get the spectra of AM, DSB-SC and SSB-SC drawn side by side once.
Digital Communications — information theory: entropy, conditional entropy, entropy rate, mutual information, capacity of the binary symmetric channel and the binary erasure channel, Huffman coding, Shannon-Fano coding, Kraft inequality, Shannon source coding theorem, Shannon channel coding theorem; PCM, DPCM, delta modulation, linear prediction filter, line coding (NRZ and RZ, unipolar and polar, Manchester) and their PSD with bandwidth; digital modulation schemes (ASK, PSK, FSK, QAM), bandwidth efficiency, average energy per bit, orthogonal basis representations, minimum distance; inter-symbol interference, eye patterns, Nyquist pulse criteria, raised cosine pulse, RRC pulse, MAP and ML detection, matched filter receiver, SNR, Cauchy-Schwarz inequality, Gram-Schmidt orthogonalization, correlation receiver, BER of digital modulation schemes; fundamentals of error correction codes, block codes, Hamming codes, CRC and convolution codes	Entropy and channel capacity are short calculations worth doing every day for a week. Hamming codes and CRC are procedural — practise, do not read.
Electromagnetics — Cartesian, cylindrical and spherical coordinates and their transformation; electrostatics: electric field and potential due to point charge, line charge and surface charge, electric flux density and capacitance; magnetostatics: magnetic induction, Faraday's law, magnetic flux density and strength, Ampere's law, Gauss' law, permeability, energy stored in a magnetic field, magnetic vector potential; Maxwell's equations in differential and integral forms and their interpretation, boundary conditions, wave equation, Poynting vector; plane waves and properties: reflection and refraction, polarization, phase and group velocity, propagation through various media, skin depth; transmission lines: equations, characteristic impedance, reflection coefficient, VSWR, impedance matching and transformation, S-parameters, Smith chart; rectangular and circular waveguides, light propagation in optical fibres, dipole and monopole antennas, linear antenna arrays	Transmission lines and the Smith chart give the most reliable numericals; Maxwell's equations are asked for their physical meaning far more often than for a derivation.

7 What the exam console gives you

No physical version of the table or the calculator is allowed inside the exam lab, so plan to use the on-screen ones (§13.11 to §13.13).

What the syllabus lists	What it means and how to prepare
Table of IS 456:2000 Code of Practice	Available on the candidate's console under the 'Useful Data' option, next to Instructions, and active throughout the examination. Close the table before you answer.
Steam Table	Same place, same rule — provided if required, so mechanical candidates should practise reading a steam table rather than memorising values from one.
Scientific calculator on the computer screen	Available for the entire duration of the examination, as a calculator icon towards the left of the candidate's application image.
