The RRB NTPC syllabus, analysed

The RRB NTPC syllabus fits on one page, and that is exactly why candidates underestimate it. Three subjects, a list of topics, and the same list for both CBTs. The difficulty is not in any one topic. It is in covering all of them to the level where you answer quickly and accurately, with a penalty for every wrong guess.

This guide reads the syllabus the way a teacher would: what each topic actually involves, where the weight lies, and how to turn the list into a plan.

The weightage

Each question carries one mark, and one-third of a mark is deducted for each wrong answer. Both tests last 90 minutes.

Worked example: time per question.

1. CBT 1: 90 minutes = 5,400 seconds. 5,400 ÷ 100 = 54 seconds per question.
2. CBT 2: 5,400 ÷ 120 = 45 seconds per question.

So CBT 2 gives you nine fewer seconds per question on average. The way to find those seconds is General Awareness: a GA question is either known or not, and should take 15 to 20 seconds. Answer 50 GA questions in about 15 minutes and you have about 75 minutes, or 64 seconds each, for the 70 Maths and Reasoning questions.

Mathematics

The syllabus lists:

What it means: most questions are arithmetic. Percentage, ratio, profit and loss, time and work, speed and interest make up the bulk, and all of them are learnable with a few formulas and steady practice. Algebra, geometry and trigonometry are at school level. Our Maths plan for NTPC takes these topics in a sensible order.

General Intelligence and Reasoning

The syllabus lists:

• analogies; completion of number and alphabet series;
• coding and decoding; mathematical operations;
• similarities and differences; relationships;
• analytical reasoning; syllogism; jumbling;
• Venn diagrams; puzzles; data sufficiency;
• statements and conclusions; statements and courses of action;
• decision making; maps; interpretation of graphs.

What it means: reasoning is usually the most scoring section. The question types repeat, and once you know the method, many take under 40 seconds. Puzzles and data sufficiency take longest; attempt them after the quick ones.

A quick example (series). Find the next term: 3, 7, 15, 31, 63, ?

1. Differences: 4, 8, 16, 32, each doubling.
2. Next difference: 64.
3. Next term: 63 + 64 = 127.
4. Check with a rule: each term is (previous × 2) + 1. 63 × 2 + 1 = 127. Both methods agree.

General Awareness

The syllabus is broad:

• current events of national and international importance;
• games and sports;
• art and culture of India, Indian literature, monuments and places;
• general science and life science up to CBSE Class 10;
• history of India and the freedom struggle;
• physical, social and economic geography of India and the world;
• Indian polity and governance: the Constitution and the political system;
• scientific and technological developments, including India's space and nuclear programmes;
• the UN and other important world organisations;
• environmental issues concerning India and the world;
• basics of computers and computer applications;
• common abbreviations;
• transport systems in India;
• the 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.

What it means: GA rewards wide reading and regular revision, not deep study. Science up to Class 10 is a large, reliable block, and NCERT science books are the best base for it. "Transport systems in India" is where railway general knowledge fits. Our General Awareness plan splits this list into weekly targets.

Negative marking: the maths of guessing

With four options and a one-third penalty, blind guessing gains nothing on average.

1. A blind guess is right 1 time in 4. Expected gain = 1/4 × 1 = 0.25.
2. It is wrong 3 times in 4. Expected loss = 3/4 × 1/3 = 0.25.
3. Net = 0.25 − 0.25 = 0.

But if you can eliminate one option with confidence, you are choosing from three:

1. Expected gain = 1/3 × 1 = 1/3.
2. Expected loss = 2/3 × 1/3 = 2/9.
3. Net = 3/9 − 2/9 = +1/9 per question.

So: do not guess blindly, but a guess after eliminating at least one option is worth taking. Our guide to negative marking covers attempt strategy in detail.

Worked example: scoring. A candidate attempts 85 questions in CBT 1: 72 right and 13 wrong. Score = 72 − 13 × 1/3 = 72 − 4.33 = 67.67 out of 100 (before normalisation).

CBT 1 versus CBT 2

Using the syllabus to plan

1. Copy the syllabus into a notebook, one topic per line.
2. Next to each topic, keep three columns: studied, practised, revised.
3. After each mock test, circle the topics where you lost marks.
4. Spend extra time on the circled topics the following week.

A tracker like this shows at a glance what is done and what is only "read once".

Practice set

1. What share of CBT 2 is General Awareness?
2. How many seconds per question does CBT 2 allow on average?
3. Next term: 2, 6, 12, 20, 30, ?
4. A candidate has 60 right and 9 wrong. What is the raw score?
5. Should you guess when you cannot eliminate any option?

Answers: 1. 50 of 120, about 42%. 2. 45 seconds. 3. 42: differences 4, 6, 8, 10, 12, or n × (n + 1) for n = 1 to 6. 4. 60 − 9 × 1/3 = 57. 5. No; the expected gain is zero and it adds risk.

What to do next

• Print the syllabus from your CEN and build the tracker.
• Take one full CBT 1 mock to find your weakest subject.
• Give GA a fixed daily slot, and Maths and Reasoning a daily practice set.
• Review the tracker every Sunday and pick three circled topics for the week.
