RPF recruits Constables (Class 10 pass) and Sub-Inspectors (graduates) through the Railway Recruitment Boards, and both posts sit the same single-paper Computer-Based Test — General Awareness, Arithmetic, and General Intelligence & Reasoning — before qualifying Physical Efficiency and Measurement Tests, document verification and a medical exam. General Awareness carries the largest share of questions, so daily current-affairs and static GK revision matters as much as solving Arithmetic and Reasoning practice sets. Every wrong answer costs one-third of a mark, so guess only when at least one option can be ruled out.

Exam Pattern

Recruiting force: Railway Protection Force (RPF), with the recruitment conducted through the Railway Recruitment Boards (RRBs). Posts: Constable and Sub-Inspector (SI). Eligibility: Class 10 pass for Constable, and graduation for Sub-Inspector; both have age limits and physical standards. Selection stages: Computer-Based Test (CBT) → Physical Efficiency Test (PET) & Physical Measurement Test (PMT) → Document Verification → Medical Examination.

CBT (single paper; same structure for Constable and SI): 120 questions, 120 marks, 90 minutes (extra time for eligible PwBD candidates with a scribe). Sections — General Awareness 50 questions/50 marks; Arithmetic 35 questions/35 marks; General Intelligence & Reasoning 35 questions/35 marks. Negative marking: one-third (1/3) mark for each wrong answer.

PET & PMT (qualifying): running, plus height and chest measurement as per the standards for the category and gender (for example, the SI and Constable running distances/timings and the height/chest norms are laid down in the notice). Candidates who qualify move to document verification and a medical examination.

This is the standard RPF CBT pattern; the exact PET timings, physical standards and vacancy split vary by notice, so always confirm against the current RPF recruitment notification on the RRB / RPF portal.

Full Syllabus

1 General Awareness
What the syllabus listsWhat it means and how to prepare
current affairs of national & international importanceCurrent affairs — news events in India and abroad read a daily newspaper or a trusted current-affairs digest and note down names, places and dates as you go.
Indian HistoryIndian History — Ancient, Medieval and Modern India including the freedom movement build a rough timeline so events, rulers and movements stay in order in your head.
Art & CultureArt & Culture — classical dance forms, music, festivals, monuments and crafts of India match each art form or monument to its region so the pairing sticks.
GeographyGeography — India's physical features, rivers, climate and world geography basics use an outline map to place rivers, mountains and states rather than only reading text.
EconomicsEconomics — basic concepts of the Indian economy such as planning, banking, budget terms and government schemes connect each term to a current news item to remember it better.
General Polity & the ConstitutionGeneral Polity & the Constitution — how India is governed: the Constitution, Parliament, the judiciary and fundamental rights learn the structure first (who does what), then the article numbers.
General Science (up to Class 10 level)General Science up to Class 10 level — Physics, Chemistry and Biology basics from school textbooks revise your own Class 9-10 NCERT science books rather than hunting for new material.
sportsSports — major tournaments, trophies, players and sporting terms from India and abroad keep a simple running list of recent winners and events as you read the news.
static general knowledgeStatic general knowledge — facts that don't change with the news, like national symbols, first-in-India records, books and authors keep these in a small revision notebook you flip through often.
2 Arithmetic
What the syllabus listsWhat it means and how to prepare
Number SystemsNumber Systems — types of numbers (natural, whole, integers, prime, composite) and how they behave.
Whole NumbersWhole Numbers — 0, 1, 2, 3 and so on, and the basic rules they follow in addition, subtraction, multiplication and division practise mental calculation with small whole numbers to build speed.
Decimals & FractionsDecimals & Fractions — converting between the two and doing basic operations on them practise converting common fractions like 1/4, 1/3, 1/8 into decimals until it's automatic.
relationship between numbersRelationship between numbers — how one number relates to another, such as multiples, factors and comparisons practising LCM and HCF questions is the most direct way to build this skill.
Fundamental arithmetical operationsFundamental arithmetical operations — addition, subtraction, multiplication and division applied together, following the correct order (BODMAS) write out each step instead of skipping ahead to avoid silly mistakes.
PercentagePercentage — expressing a part out of a hundred and converting between percentage, fraction and decimal memorise the fraction equivalents of common percentages like 12.5%, 25%, 33.33% to calculate faster.
Ratio & ProportionRatio & Proportion — comparing two quantities and solving problems where quantities scale together.
AveragesAverages — finding the mean of a set of numbers, and questions where one value changes and the average shifts learn the shortcut for how the average moves when one term is replaced.
InterestInterest — calculating simple and compound interest on a sum of money over time keep the formulas for both types side by side and practise telling from the question which one applies.
Profit & LossProfit & Loss — cost price, selling price and the profit or loss percentage on a transaction always work out whether the percentage is calculated on cost price or selling price before you start.
DiscountDiscount — the reduction given on a marked price before the final selling price is fixed remember that discount is calculated on the marked price, not on the cost price.
MensurationMensuration — finding the area, perimeter and volume of shapes like squares, circles, cubes and cylinders keep a single formula sheet for all shapes and revise it until you don't need to think twice.
Time & WorkTime & Work — how long a person or a group takes to finish a task, and how combined work speeds things up.
Time & DistanceTime & Distance — speed, time and distance problems, including trains, boats and relative speed.
Tables & GraphsTables & Graphs — reading and interpreting data shown in tables, bar graphs and pie charts practise picking out only the numbers the question actually asks for, without reading the whole table.
3 General Intelligence & Reasoning
What the syllabus listsWhat it means and how to prepare
AnalogiesAnalogies — finding how one pair of words or figures relates, then applying the same relationship to a new pair first name the relationship out loud (opposite, part-whole, use) before picking the answer.
Similarities & DifferencesSimilarities & Differences — spotting what makes a set of items alike or the one item that doesn't fit check every item against the same single property instead of jumping between properties.
Spatial Visualisation & OrientationSpatial Visualisation & Orientation — imagining how a shape looks when rotated, folded or seen from another direction sketch the shape roughly on paper before choosing an answer rather than only visualising it in your head.
Problem SolvingProblem Solving — working through a situation step by step to reach a logical answer break the question into small steps on rough paper instead of trying to solve it all in one go.
Analysis & JudgementAnalysis & Judgement — reading given facts carefully and deciding what conclusion they support base your answer only on what's stated in the question, not on outside assumptions.
Decision MakingDecision Making — choosing the most sensible action from the options given a set of conditions underline the conditions first, then eliminate the options that clearly break one of them.
Visual MemoryVisual Memory — recalling a figure, pattern or arrangement after briefly looking at it practise glancing at a picture for a few seconds and then redrawing it from memory.
DiscriminationDiscrimination — telling apart figures or items that look almost identical, with one small difference scan each option corner by corner instead of glancing at it as a whole.
ObservationObservation — noticing details in a figure, picture or short passage accurately the answer is usually hidden in a small detail, so read or look twice before answering.
Relationship conceptsRelationship concepts — working out family or positional relationships from given clues, like blood-relation puzzles draw a simple family tree or diagram on rough paper rather than tracking it in your head.
Arithmetical ReasoningArithmetical Reasoning — logic-based word problems that use basic maths to reach a conclusion read the question twice to identify exactly what is being asked before doing any calculation.
Verbal & Figure ClassificationVerbal & Figure Classification — picking the word or figure that doesn't belong with the rest of the group identify the common rule linking the majority first, then find the odd one out.
Arithmetic Number SeriesArithmetic Number Series — spotting the pattern in a sequence of numbers to find the missing or next term check the difference between consecutive terms first, then try ratios or squares if that doesn't work.
Coding-DecodingCoding-Decoding — figuring out the rule that turns one word or number into a code, then applying it in reverse write the letters with their position numbers (A=1, B=2...) alongside the question to spot the shift quickly.
Statement-ConclusionStatement-Conclusion — deciding which conclusions logically follow from a given statement judge each conclusion only against what the statement actually says, not against real-world general knowledge.
Syllogistic ReasoningSyllogistic Reasoning — drawing a valid conclusion from two or more given premises using set logic draw simple Venn diagrams for each premise, it makes the valid conclusion easy to see.
