This is the topic list RRB prints in its detailed notices for NTPC. We compared the Graduate notice (CEN 06/2025) and the Undergraduate notice (CEN 07/2025) and the lists are identical. We have not added topics the notices do not name; study advice is labelled as ours. Marks, timing and negative marking are on the exam pattern page.
Syllabus at a glance
| Stage | Subjects | Questions (1 mark each, 1/3 negative) |
|---|---|---|
| CBT-1 | General Awareness, Mathematics, General Intelligence and Reasoning | 40 + 30 + 30 = 100 in 90 minutes |
| CBT-2 | the same three subjects, same topic list | 50 + 35 + 35 = 120 in 90 minutes |
| CBAT (Station Master, Traffic Assistant) | aptitude test batteries, T-score 42 minimum in each | pattern is on the RDSO site, not in the CEN |
| Typing test (typist posts) | typing in English or Hindi, qualifying | 30 WPM English or 25 WPM Hindi |
The notices call the section distribution "only indicative", so the real paper can vary a little from these counts.
Level of questions. The CEN says CBT-1 is of screening nature and that question standard will generally be in line with the educational standard prescribed for the post. For graduate posts that means a degree; for undergraduate posts, Class 12.
Mathematics
The notices list, in this order: Number System, Decimals, Fractions, LCM, HCF, Ratio and Proportions, Percentage, Mensuration, Time and Work, Time and Distance, Simple and Compound Interest, Profit and Loss, Elementary Algebra, Geometry and Trigonometry, Elementary Statistics, "etc."
Grouped for planning:
- Number work: number system, decimals, fractions, LCM and HCF.
- Arithmetic: ratio and proportion, percentage, simple and compound interest, profit and loss, time and work, time and distance.
- Geometry and mensuration: mensuration, geometry, trigonometry.
- Algebra and statistics: elementary algebra, elementary statistics.
Our note: the word "etc." means topics outside this list can appear, but the list is the official core. Arithmetic has the most named topics, so it is the largest block to build first.
General Intelligence and Reasoning
Named in the notices: Analogies, Completion of Number and Alphabetical Series, Coding and Decoding, Mathematical Operations, Similarities and Differences, Relationships, Analytical Reasoning, Syllogism, Jumbling, Venn Diagrams, Puzzle, Data Sufficiency, Statement-Conclusion, Statement-Courses of Action, Decision Making, Maps, Interpretation of Graphs, "etc."
Grouped for planning:
- Series and patterns: number and alphabetical series, analogies, similarities and differences.
- Coding and operations: coding and decoding, mathematical operations, jumbling.
- Logic: syllogism, Venn diagrams, statement-conclusion, statement-courses of action, analytical reasoning, puzzle, data sufficiency, decision making.
- Relationships and data: relationships, maps, interpretation of graphs.
Our note: unlike some other exams, the list does not name figure-based topics such as paper folding or embedded figures. We only prepare what is named, then watch your mocks for anything extra.
General Awareness
The CEN list for General Awareness is the longest of the three. In its own words, the questions are likely to include:
- Current events of national and international importance.
- Games and sports.
- Art and culture of India; Indian literature; monuments and places of India.
- General science and life science (up to Class 10 CBSE).
- History of India and the freedom struggle.
- Physical, social and economic geography of India and the world.
- Indian polity and governance, including the constitution and the political system.
- General scientific and technological developments, including the space and nuclear programmes of India.
- The UN and other important world organisations.
- Environmental issues concerning India and the world at large.
- Basics of computers and computer applications.
- Common abbreviations.
- Transport systems in India.
- Indian economy.
- Famous personalities of India and the world.
- Flagship government programmes.
- Flora and fauna of India.
- Important government and public sector organisations of India.
General Awareness is 40 of 100 marks in CBT-1 and 50 of 120 in CBT-2. Our note: that is 40% and about 42% of the paper, more than either of the other two subjects, and the list includes items such as transport systems, flagship programmes and public sector organisations that are easy to overlook if you prepare from a generic GK book.
CBAT (Station Master and Traffic Assistant)
After CBT-2, candidates for these two posts take the Computer Based Aptitude Test. The CEN states:
- You need a minimum T-score of 42 in each test battery, with no relaxation for any category.
- Questions and answer options are in English and Hindi only, and there is no negative marking.
- The CEN refers candidates to the Psycho Technical Directorate section of the RDSO website for question patterns and other details.
We have not read the RDSO guidelines, so this page does not list the batteries.
Typing skill test
For the typist posts, the qualifying test requires 30 words per minute in English or 25 words per minute in Hindi, on a computer without editing tools or spell check. Hindi typing offers Kruti Dev and Mangal fonts. The marks are not added to merit. Practise on our NTPC typing test.
How to use this syllabus
- Tick it off by subject. Three subjects share one 90-minute clock, so a weak subject costs as much as a strong one gains.
- Start General Awareness early and keep it daily. It is the largest block and the only one with current events.
- Test each topic as you finish it. Pareeksha's topic-wise practice is organised by topic (Pro). A free 10-question mini-mock lets you try the format. Full mocks and previous-year papers are Pro.
- Re-check the notice. RRB can issue a new CEN with changes. Compare this page's "as on" date with the Graduate CEN and Undergraduate CEN before a new cycle.
What this page does not have
- The CBAT batteries (the CEN defers to RDSO).
- Any sub-topic weightage. The notices give no chapter-wise weightage, and we do not estimate one.
- The earlier cycle (CEN 05/2024 and 06/2024). We did not read those notices.
