RRB NTPC CBT-2 Strategy: Section-Wise Plan, Mocks and 45 Days

For most graduate-level NTPC aspirants, CBT-1 is a hurdle and CBT-2 is the real exam. The first paper decides who gets to sit the second. The second decides your rank. Yet many candidates spend the weeks after CBT-1 doing the same revision they did before it, in the same way, at the same speed. That is the quickest way to waste the most valuable window of the whole recruitment cycle.

This guide is about that window. It explains what CBT-2 actually looks like, how it differs from CBT-1 in ways that change your tactics, how to handle each section, what the post-CBT-2 skill stages mean for you, and how to run 45 days of preparation with a sensible mock schedule. Where a fact could not be confirmed from an official source, we say so and ask you to check the latest notification.

Where CBT-2 Sits in the NTPC Process

The current NTPC cycle (2026-27) has been announced with separate notices for graduate-level and undergraduate-level posts. Online applications for the graduate cycle were announced to open on 8 October 2026, and CBT-1 is tentatively expected in December 2026 to January 2027. Treat all dates as tentative until the detailed notification and exam-city intimation say otherwise.

The broad stage structure has stayed the same for several cycles:

1. CBT-1: a screening test for all applicants.
2. CBT-2: the main merit test for those who clear the CBT-1 shortlist.
3. Post-specific stage: a Typing Skill Test for typist and clerk posts, or a Computer Based Aptitude Test (CBAT) for Station Master. Some posts go straight to documents.
4. Document verification and medical examination.

The key point for strategy: for most graduate posts, the final merit is built mainly on CBT-2 performance. Skill stages are largely qualifying, except for Station Master where CBAT carries a weightage (explained below). So a mark gained in CBT-2 is a mark that directly moves your rank.

CBT-2 Pattern: What Is Verified

The graduate-level CBT-2 pattern, as reported consistently across the previous cycle's coverage and the current cycle's announcements, is this:

Section	Questions	Marks
Mathematics	35	35
General Intelligence and Reasoning	35	35
General Awareness	50	50
Total	120	120

• Duration: 90 minutes (120 minutes for eligible PwBD candidates using a scribe).
• Negative marking: one-third of a mark for each wrong answer. No deduction for unattempted questions.
• Marks per question: one mark each.

Two cautions. First, we could not open the official detailed notice of the current cycle while writing this, so confirm the numbers above against the detailed CEN when it is released. Second, details such as whether sections are separately timed, the minimum qualifying percentage in CBT-2, and the shortlisting ratio for the next stage are set by each notification. Do not rely on a coaching page or a friend for these. Check the latest notification.

Some coaching sources quote minimum qualifying marks of 40 percent for UR and EWS, 30 percent for OBC (non-creamy layer) and SC, and 25 percent for ST. That is a floor to be considered, not a target. In practice, merit cut-offs in a competitive zone sit well above any minimum, and the minimum itself should be confirmed in the notice.

How CBT-2 Differs from CBT-1

Our earlier post covered the differences briefly. Here is the longer, practical version.

Aspect	CBT-1	CBT-2
Purpose	Screening for the next stage	Merit ranking for final selection
Questions	100 (GA 40, Maths 30, Reasoning 30)	120 (GA 50, Maths 35, Reasoning 35)
Duration	90 minutes	90 minutes
Time per question	About 54 seconds	About 45 seconds
Negative marking	1/3	1/3
Competition	Whole applicant pool	Only shortlisted candidates, all of whom are already decent scorers

The pattern table hides the more important differences. These are the ones that change how you should prepare.

1. Time per question drops

Do the arithmetic: 100 questions in 90 minutes is 0.9 minutes each. 120 questions in 90 minutes is 0.75 minutes each. That is 45 seconds per question, on average, for a paper that includes long reasoning sets and multi-step maths. The only way to make this work is to answer General Awareness much faster than the average. That is why GA is the lever for time.

2. General Awareness becomes a bigger share

GA is 40 percent of CBT-1 (40 of 100) and about 42 percent of CBT-2 (50 of 120). It is also the section where speed is the cheapest to buy. A candidate who knows a fact answers in 10 seconds; a candidate who does not wastes 30 seconds and still guesses. Fifty marks from GA is the most reliable way to build a margin.

3. The pool is stronger

Everyone in CBT-2 cleared CBT-1. A score that looked safe in CBT-1 is simply average here. The ranking now depends on small differences, which makes accuracy and negative marking matter far more.

4. Difficulty is a stage-level claim you should test yourself

Many sources say CBT-2 is tougher. That may hold for some cycles and not others. Rather than trust the claim, use your own mock data: if your CBT-2-pattern mocks consistently score lower than your CBT-1 mocks at the same preparation level, the paper is harder for you, and that is the useful fact.

5. Stamina matters

Staying accurate over 120 questions is a different skill from staying accurate over 100. Your concentration in the last 20 minutes is where careless errors enter.

6. Post-specific stages follow

After CBT-1 you only had to qualify. After CBT-2 you may have to type, take an aptitude battery, or both, depending on your post. Planning that early, rather than after the result, is part of CBT-2 strategy.

Normalisation: The Basics

The exam is held in multiple sessions across several days. No two question papers are identical in difficulty, so Railway Recruitment Boards apply a normalisation procedure to put marks from different sessions on a common scale. The exact method is published in the notification and in the board's notice. What matters to you is the effect, not the formula.

• Your raw score is not your final score. The score used for merit is the normalised score.
• If your session paper was harder than others, normalisation tends to compensate, and if it was easier, it tends to adjust the other way. You cannot choose your session, so do not waste energy guessing which one is easier.
• Normalisation works on the performance of the group in your session. The only thing in your control is your own raw score: more correct answers, fewer wrong ones.
• Social-media estimates of normalised cut-offs are guesses. Wait for official result documents.

We have not reproduced a formula here because we could not verify the one currently in force. Check the latest notification for the method statement.

The Math of Negative Marking

With a one-third deduction, accuracy beats volume. Compare these candidates, all of whom you can verify with a calculator.

Candidate	Attempted	Accuracy	Correct	Wrong	Score
A	100	75%	75	25	75 - 8.33 = 66.67
B	90	85%	76.5	13.5	76.5 - 4.5 = 72.0
C	80	95%	76	4	76 - 1.33 = 74.67

(Fractions of questions are used only to illustrate; real scores are whole numbers of correct and wrong answers.) Candidate C attempted twenty fewer questions than A and scored about eight marks more. Aim for the C profile.

When is guessing worth it?

If you blindly guess among four options, the expected gain is zero: a one-in-four chance of +1 and a three-in-four chance of -1/3 is (1/4) - (3/4)(1/3) = 0. If you can eliminate one option, your chance is one in three, and the expected value is (1/3) - (2/3)(1/3) = 1/9, a small positive. If you can eliminate two options, the chance is one in two and the expected value is (1/2) - (1/2)(1/3) = 1/3, a clear positive. The rule: guess only after genuine elimination, never blind.

Time Plan for the 90 Minutes

This is a planning suggestion based on the number of questions, not an official rule. Adjust after your own mocks.

Block	Suggested time	Logic
General Awareness (50 Q)	15 to 18 minutes	Fast recall; do not linger
Reasoning (35 Q)	25 to 27 minutes	Pick easy sets first
Mathematics (35 Q)	30 to 33 minutes	Skip long-calculation questions
Review of marked questions	10 to 12 minutes	Second pass only on questions you can crack

If your exam interface lets you move freely between sections, many candidates start with GA to bank quick marks, then Reasoning, then Maths. If sections turn out to be locked or separately timed in the notice, follow the notice. Whichever order you choose, practise the same order in every mock so that it becomes automatic.

The two-pass habit

• Pass 1: answer what you can solve within about 40 seconds. Mark the rest for review. Do not argue with a question.
• Pass 2: return to marked questions. Eliminate options, then decide to answer or leave.

Target Score Logic (A Planning Suggestion)

We will not claim a cut-off here. Cut-offs differ by zone, category, post and year, and the current cycle has not produced one. Look at official result documents of previous cycles for your RRB zone. What you can do now is set section targets that are aggressive but realistic, then adjust.

Section	Questions	Suggested attempts	Suggested accuracy target
General Awareness	50	40 to 45	85% or more
Reasoning	35	28 to 32	85% or more
Mathematics	35	25 to 30	85% or more

For example, suppose you attempt 42 in GA at 88 percent (37 correct, 5 wrong), 30 in Reasoning at 87 percent (26 correct, 4 wrong) and 27 in Maths at 85 percent (23 correct, 4 wrong). That is 86 correct and 13 wrong, which gives 86 - 13/3 = 81.67 marks out of 120. Whether that is enough depends on your zone and category. The point is the structure: 99 attempts, high accuracy, no heroics.

Use your mock-test history to see how your score moves when you change the number of attempts. Plot attempts against accuracy for your last ten tests. The ideal point is usually where you stop gaining marks from extra attempts.

Section Strategy: General Awareness (50 Questions)

General Awareness is the section where preparation converts to marks most directly. The syllabus listed for the paper covers current events, games and sports, art and culture, Indian literature, monuments and places, general science and life science (up to Class X level), history, Indian polity and governance including the Constitution and political system, economic geography and resources, general scientific and technological developments, and similar topics.

What to prioritise

• Current affairs of the last 6 to 9 months before the exam: appointments, awards, sports events, summits, government schemes, defence, and Indian Railways news. Make a short one-page revision per month.
• General science: NCERT-level physics, chemistry and biology. Railway papers have historically leaned on basic facts, definitions, units, diseases and nutrition.
• Polity and economy: fundamental rights, directive principles, important articles, constitutional bodies, banking and budget basics.
• History, geography, culture: repeated static facts such as dynasties, movements, rivers, soils, national parks, dance forms and festivals.

How to practise

• Do GA in timed blocks of 50 questions in 15 minutes. If you cannot do it, cut your reading time and revise through questions, not notes.
• Keep an error log with the fact, the source and a one-line memory hook.
• Revise the log every week. Facts stay when they are revisited, not when they are read once.
• Do not attempt a question where you cannot eliminate at least two options.

GA mistakes to avoid

• Reading monthly magazines from cover to cover without testing recall.
• Skipping static GK because "current affairs matter more".
• Collecting too many sources. One reliable monthly capsule plus quizzes is enough.

Section Strategy: Reasoning (35 Questions)

Reasoning is where candidates with good practice outperform those with good ability. The topics are finite and the question types repeat. Typical areas in the syllabus include analogies, alphabetical and number series, coding and decoding, mathematical operations, relationships, syllogism, jumbling, Venn diagrams, data interpretation and sufficiency, conclusions and decision making, similarities and differences, analytical reasoning, classification, directions, statements and arguments, and statements and assumptions.

Order of attack

1. Fastest first: analogy, classification, number and letter series, odd one out, directions, ranking. Each should take under 30 seconds with practice.
2. Medium: coding-decoding, blood relations, Venn diagrams, syllogism, mathematical operations.
3. Longest last: seating arrangements, puzzles, data sufficiency and any set with more than four questions on the same data.

Practical tips

• For a puzzle set, spend a fixed 20 seconds reading it. If the structure is not clear, skip. A set of four or five questions on one puzzle is an all-or-nothing investment.
• Use the on-screen rough work area only for diagrams and tables. Do not rewrite the whole question.
• Learn five or six standard formats for syllogism and Venn diagrams so that you recognise a question type instead of solving it fresh.
• For series and coding, write the letter positions once and memorise the opposite-letter pairs (A-Z, B-Y and so on).

Reasoning mistakes to avoid

• Spending three minutes on one arrangement question that carries one mark.
• Solving every question by a long method when a short pattern check works.
• Skipping figure-based questions out of habit; these are often quick for those who practise them.

Section Strategy: Mathematics (35 Questions)

Maths is where a time-per-question budget hurts most. Even an average question can take over a minute. That makes selection of questions the central skill of the section.

Syllabus areas to cover

• Number system, BODMAS, decimals and fractions, LCM and HCF
• Ratio and proportion, percentages
• Mensuration
• Time and work, time and distance
• Simple and compound interest
• Profit and loss
• Elementary algebra, geometry and trigonometry
• Elementary statistics
• Square root, age calculations, calendar and clock, pipes and cisterns

How to select questions

• Read the question, decide in about five seconds whether you know the method. If not, mark it and move on.
• Prefer questions where the answer can be reached by a percentage, a fraction or a ratio shortcut.
• Skip questions with heavy decimal multiplication unless you are fast at it; use option elimination to check approximate values.
• Keep a fixed time limit per question, such as 60 seconds. If you are not close, move on.

Speed builders

• Know squares up to 30, cubes up to 15, and tables up to 20.
• Memorise common fraction-percentage pairs, such as 1/7 equals about 14.28 percent and 1/8 equals 12.5 percent.
• Learn the LCM method for time and work, and the fraction method for percentages. Both are covered in our separate posts on these topics.
• Do 20 timed questions daily from one chapter. Record both time and accuracy.

Maths mistakes to avoid

• Reading units carelessly (km/h against m/s, years against months).
• Choosing an answer that matches an intermediate step. Examiners often include such options deliberately.
• Ignoring chapters because they look hard; geometry and trigonometry are a handful of questions, but algebra identities can be quick marks.

After CBT-2: Typing Skill Test and CBAT in Brief

Which extra stage you face depends on the post. The post lists for the new cycle will be in the detailed notification, so treat the grouping below, drawn from the previous cycle's structure, as a guide. A separate Pareeksha post covers these tests in depth.

Post type	Stage after CBT-2
Junior Account Assistant cum Typist, Senior Clerk cum Typist (graduate); Accounts Clerk cum Typist, Junior Clerk cum Typist (undergraduate)	Typing Skill Test (qualifying), then documents
Station Master	CBAT, then documents
Goods Train Manager, Chief Commercial cum Ticket Supervisor (graduate); Commercial cum Ticket Clerk, Trains Clerk (undergraduate)	Normally documents directly after CBT-2; confirm in the notice

Typing Skill Test

Reported standards, which you must confirm in the notice: 30 words per minute in English or 25 words per minute in Hindi, tested over a 10-minute timed passage after a short practice period. Coverage also reports that transcripts of candidates who fall short of the minimum typed volume are not evaluated. The test is qualifying in nature, so it does not add marks to your merit, but failing it ends your candidature for that post.

Practical points: the test uses a computer keyboard, so practise on a physical keyboard and not a phone. If you choose Hindi, check which layout and font the test uses in the instructions issued by your RRB. Start practising in the CBT-2 window, because speed gains come from steady daily typing and not last-minute cramming.

CBAT for Station Master

Station Master is reported to be the one post that needs CBAT. Reported details, to be confirmed in the notice: candidates equal to about eight times the vacancies are shortlisted on CBT-2 performance; the CBAT consists of several test batteries; a minimum T-score of 42 is required in each battery, with no category relaxation; and the final merit is 70 percent CBT-2 and 30 percent CBAT. There is no negative marking in CBAT.

Two implications. First, if Station Master is your target, CBT-2 still drives 70 percent of your merit. Second, CBAT cannot be crammed in a night, but a few weeks of practice with attention and perceptual-speed tasks helps you feel at ease.

The 45-Day Plan After CBT-1

This plan assumes you have about 45 days between the CBT-1 attempt and CBT-2 or the CBT-1 result. Real gaps vary, and in some cycles the gap has been longer, so stretch or compress the weeks, keeping the order. It is a planning suggestion, not an official schedule.

Days 1 to 3: Diagnose

• Write down your CBT-1 memory: sections that felt slow, questions you skipped, topics that surprised you.
• Take one full 120-question mock under exact conditions. This is your baseline.
• Analyse by section: attempts, accuracy, time taken, and the type of each error (concept gap, careless slip, ran out of time, guessed).

Days 4 to 15: Fix the weakest chapters

• Maths (about 90 minutes a day): two chapters per three days, starting with your weakest high-frequency ones. Finish with 20 timed questions.
• Reasoning (about 45 minutes a day): rotate question types; do one type for 25 questions, then another.
• GA (about 60 minutes a day): alternate static GK and science days; add 20 minutes of current affairs daily.
• One sectional test every third day.

Days 16 to 30: Build speed and accuracy

• Shift from learning to timed practice. Maths in sets of 35 in 30 minutes, Reasoning in sets of 35 in 25 minutes, GA in sets of 50 in 15 minutes.
• Start the revision loop: every Sunday, revise the error log of the week.
• Begin daily typing practice of 15 to 20 minutes if your target post involves typing.
• Take a full mock every fourth day, followed by a thorough analysis lasting at least as long as the test.

Days 31 to 40: Mock-heavy phase

• A full mock every second day, with sectional tests on the alternate days.
• Revise only from your error log, formula sheet and one-page current-affairs summaries.
• Practise the two-pass method until it is automatic.

Days 41 to 45: Consolidate

• Two full mocks, spaced well apart, plus light revision.
• Re-read your formula sheet, your list of repeated mistakes and your last month of current affairs.
• Check the admit card, exam city, ID documents and travel plan. Sleep properly. No new topics in the last two days.

If you are still waiting for CBT-1 results, treat this plan as general preparation. Do not wait for the result to begin; the CBT-2 syllabus covers the same subject areas as CBT-1.

Weekly Template

Wednesday	Sectional test (one section), analysis, error log
Thursday	Maths chapter, Reasoning practice, GA science
Friday	Weak-topic revision, typing practice
Saturday	Full-length mock in exam conditions
Sunday	Mock analysis, error-log revision, weekly current affairs review

Mock Test Schedule and How to Analyse a Mock

Phase	Full mocks	Sectional tests
Days 1 to 15	1 baseline plus 1	One every third day
Days 16 to 30	One every fourth day	Two a week
Days 31 to 40	One every second day	Alternate days
Days 41 to 45	Two	None or light

A mock is only useful if you analyse it. Spend at least as long on the analysis as on the test. For each mock record:

• Attempts, correct, wrong and score by section.
• Time spent per section against the plan.
• Each wrong answer tagged: concept gap, calculation slip, misread question, or guess.
• Each skipped question that you could have solved. This tells you if you are too cautious.

Look at the trend over three or four mocks, not at a single score. A single bad mock is often a bad day, and a single high one proves nothing.

Common Mistakes in CBT-2 Preparation

• Treating CBT-1 clearance as the finish line. The merit is built in CBT-2.
• Taking mocks without a pattern match. Use 120-question, 90-minute mocks with the correct section split.
• Chasing attempts. Attempting everything at 70 percent accuracy loses to attempting less at 90 percent.
• Ignoring GA until the last month. It is 50 marks and takes sustained revision.
• Not logging errors. Repeating the same mistake is the most expensive habit.
• Guessing blind. Blind guesses have zero expected value and add variance.
• Delaying typing practice. If your post needs typing, the skill takes weeks, not days.
• Believing rumours on normalisation and cut-offs. Rely on official documents.
• Changing sources every week. Pick one book per subject and finish it.
• Neglecting health. A 90-minute test needs sleep and focus more than one more hour of study.

Exam-Day Checklist

• Carry the admit card and the ID listed in it. Read the instructions for the centre and reporting time.
• Reach early. Log in calmly and check the on-screen instructions before you start the timer.
• Start with your planned order. Use the two-pass method. Keep an eye on the clock after each block.
• Use the final 10 minutes to review marked questions only.
• After the paper, do not discuss answers; move to the next stage of preparation if relevant.

FAQs

What is the RRB NTPC CBT-2 exam pattern? The graduate-level CBT-2 has 120 questions for 120 marks in 90 minutes: Mathematics 35, Reasoning 35, General Awareness 50. Confirm in the latest notification.

Is there negative marking in CBT-2? Yes, one-third of a mark is deducted for each wrong answer. There is no deduction for unattempted questions.

How is CBT-2 different from CBT-1? CBT-2 has more questions (120 against 100), less time per question, a larger General Awareness share, a stronger competition pool and it decides your merit, while CBT-1 only screens.

Is the CBT-2 syllabus different from CBT-1? The subject areas are the same: Mathematics, Reasoning and General Awareness. The question mix and the pressure differ, so practise on CBT-2 pattern papers.

Does the typing test add marks to my merit? It is a qualifying test for typist posts, as reported for the previous cycle. Check the notification for how it is treated this year.

Which post needs CBAT? Station Master, as reported for the previous cycle, with a 70 percent CBT-2 and 30 percent CBAT weightage. Verify in the notice.

What is normalisation and will it affect me? It adjusts marks across sessions so that candidates are compared fairly. Your merit uses the normalised score. You can only control your raw score.

What should I do if my CBT-1 result is delayed? Do not pause. Keep the 45-day plan going, since the subject areas are the same.

How many mocks should I take before CBT-2? The schedule above gives roughly 12 to 15 full-length mocks in 45 days plus sectional tests. Quality of analysis matters more than the number.

What score should I aim for? Cut-offs vary by zone, category and post, and the current cycle has not yet produced one. Check previous official result documents for your zone, and use your mocks to push accuracy above 85 percent.

Final Word

CBT-2 rewards steady work done in the weeks after CBT-1: a baseline mock, an honest error log, timed sections, and a mock schedule you actually follow. Practise with full-length mocks and sectional tests on Pareeksha, analyse each one properly, and walk into the exam with a plan for every minute.
