Railway GA: Exam Pattern, Scoring and Question Framing
This chapter sets out what the General Awareness section is in RRB NTPC and RRB Group D Level 1: how many questions it carries, how many marks each is worth, how long the paper runs and what a wrong answer costs. It then maps the official GA topic list onto the nine chapters of this book and shows how the questions are framed, so that every later chapter is read against the paper you will actually sit.

Where General Awareness sits in NTPC CBT 1 and CBT 2
The NTPC graduate recruitment under CEN 05/2024 has two computer based tests. CBT 1 has 100 questions of one mark each: General Awareness 40, Mathematics 30 and General Intelligence and Reasoning 30, in 90 minutes. Its normalised score decides who is shortlisted for CBT 2, which has 120 questions (General Awareness 50, Mathematics 35, General Intelligence and Reasoning 35) in the same 90 minutes. The notice describes CBT 1 as being of screening nature. The table sets out both stages side by side.
Each question carries one mark, so General Awareness is worth 40 marks in CBT 1 (40% of the paper) and 50 in CBT 2 (about 41.7%). Clause 13.1 says the section-wise distribution is only indicative, so 40 GA questions is a planning figure. The minimum marks for eligibility are UR 40%, EWS 40%, OBC (non-creamy layer) 30%, SC 30% and ST 25%, relaxable by 2 marks for PwBD candidates where vacancies are short. The notice gives one minimum per category, not one per section.
CEN 06/2026 (Graduate) is a later cycle. A secondary summary retrieved on 8 October 2026 reports the same pattern: CBT 1 with General Awareness 40, Mathematics 30 and General Intelligence and Reasoning 30; CBT 2 with 50, 35 and 35; 90 minutes; and one-third mark deducted for each wrong answer. The same summary reports an application window of 8 October to 6 November 2026. The detailed notice was not checked for this edition, so treat these figures as reported, not verified, and confirm them before you plan around them.
| Stage (CEN 05/2024) | General Awareness | Mathematics | General Intelligence and Reasoning | Total questions | Duration |
|---|---|---|---|---|---|
| NTPC CBT 1 | 40 | 30 | 30 | 100 | 90 minutes (120 minutes for eligible PwBD candidates with a scribe) |
| NTPC CBT 2 | 50 | 35 | 35 | 120 | 90 minutes (120 minutes for eligible PwBD candidates with a scribe) |
Group D Level 1: a 20-question General Awareness and Current Affairs section
The Group D Level 1 test under CEN 09/2025 is a computer based test of 100 questions, one mark each, in 90 minutes (120 minutes for candidates eligible for a scribe). The notice splits the questions into General Science 25, Mathematics 25, General Intelligence and Reasoning 30 and General Awareness and Current Affairs 20. It describes the exam as a single stage CBT but reserves the right to conduct it in multiple stages. Where a second stage is held, the first stage may be treated as a qualifying test for shortlisting.
The General Awareness heading in the Group D notice is worded differently from the NTPC list. Clause 14.1(d) reads 'General Awareness on current affairs in Science & Technology, Sports, Culture, Personalities, Economics, Politics and any other subject of importance', and the notice says the topics are illustrative and not necessarily exhaustive. Expect the same ground as NTPC GA. At 20 questions the section is half the size of NTPC's 40-question GA block, so five missed questions are a quarter of the section, against an eighth of the NTPC CBT 1 block.
The Group D shortlisting minimums in clause 14.1 are UR 40%, EWS 40%, OBC (non-creamy layer) 30%, SC 30% and ST 30%. The ST figure is higher than the NTPC CBT 1 eligibility figure of 25%, one of the traps in section 5. The notice also says normalisation of marks will be done for CBTs held in multiple shifts, but it does not say how, so this book states no normalisation formula and a raw score is a weak guide to rank.
| Section (CEN 09/2025 Level 1) | Questions | Share of the 100 |
|---|---|---|
| General Science (Physics, Chemistry and Life Sciences to 10th CBSE level) | 25 | 25% |
| Mathematics | 25 | 25% |
| General Intelligence and Reasoning | 30 | 30% |
| General Awareness and Current Affairs | 20 | 20% |
| Total | 100 | 100% |
Negative marking: what one-third of a mark does to your score
Both notices state the same rule: one-third of a mark is deducted for each wrong answer (NTPC clauses 13.1 and 13.2.1; Group D clause 14.1). The notice deducts only for wrong answers, so an unattempted question neither adds nor subtracts. The raw score is therefore the number of correct answers minus one-third of the number of wrong answers. With C correct and W wrong, each worth one mark, the score is C minus W divided by 3. The same formula gives a section score, such as the General Awareness block alone.
The rule decides whether guessing helps. Let p be the chance that an attempted question is right. Each attempt then has an expected value of p × 1 minus (1 − p) × 1/3, which simplifies to (4p − 1) ÷ 3. This is positive only when p is above one quarter. With four options and no information, a blind guess has p equal to one quarter, so the expected gain is exactly zero. A random guess among four options is therefore a gamble with no average benefit.
Elimination changes the arithmetic. With one option removed, three remain and a blind guess has p equal to one third, so the expected value is (4 × 1/3 − 1) ÷ 3, which is 1/9 of a mark, about 0.11, per guess. With two options left, p is one half and the expected value is one third of a mark per guess. A guess with four live options gains nothing on average, so the number of options you can remove decides whether a guess is worth making.
The same formula applies to a whole paper. Suppose you attempt 100 questions. At 60% accuracy each attempt is worth (4 × 0.6 − 1) ÷ 3, about 0.467 of a mark, so 100 attempts give 46.7 marks. At 70% the total is 60 marks, and at 80% it is 73.3 marks. Moving from 60% to 70% adds 13.3 marks, while ten more attempts at 60% add only 4.7. Accuracy on attempted questions is worth more than volume at a weak rate, so a careful pass usually beats a rushed attempt at everything.
| Options still in play | Chance a blind guess is right (p) | Expected marks per guess | What it means |
|---|---|---|---|
| 4 | 1/4 (0.25) | 0 | No average gain |
| 3 | 1/3 (0.33) | 1/9 (about 0.11) | Small gain |
| 2 | 1/2 (0.50) | 1/3 (about 0.33) | Clear gain |
Mapping the official GA syllabus list to the nine chapters
The NTPC notice lists General Awareness topics in clause 13.1(c) for CBT 1 and clause 13.2.1(c) for CBT 2. The two lists contain the same 20 items. The notice introduces them with 'likely to include' and ends with 'etc.', so the list is a guide to the ground rather than a closed syllabus. The table gives the chapter that owns each item. Item 20 is split across three chapters, because its wording covers constitutional bodies, public sector enterprises and railway and defence organisations.
The Group D heading in clause 14.1(d) maps the same way. 'Science and Technology' belongs to chapter 6, 'Sports' and 'Personalities' to chapter 8, 'Culture' to chapter 7, 'Economics' to chapter 5, and 'Politics' to chapter 3. Current affairs in the Group D wording is taught by the method and dated items in chapter 9. The heading ends with 'any other subject of importance', so a Group D question can fall outside every listed row. Identify the subject first, then go to the chapter whose notes hold the underlying fact.
Item 20 deserves a method of its own, because it is the one most often misfiled. Before you work a question on it, decide which kind of organisation it names. A constitutional or statutory body, such as the Election Commission of India, is a chapter 3 question. A public sector enterprise, including a Navratna or Maharatna company, is chapter 5. A railway or defence organisation, such as the Railway Board, is chapter 9. The decision tells you which chapter's notes to reread after a wrong answer.
