RRB NTPC Undergraduate CBT-1 2026

Learning outcomes

By the end of this lesson, you should be able to:

• describe the CEN 07/2025 CBT-1 pattern without relying on coaching-site summaries;
• map every study block to Mathematics, General Intelligence and Reasoning, or General Awareness;
• calculate the effect of the one-third negative mark;
• separate stable syllabus facts from time-sensitive exam notices; and
• build a diagnostic-led weekly plan instead of studying every topic equally.

1. Use the right evidence

This study plan is aligned to RRB CEN 07/2025 for NTPC Undergraduate posts. Treat the detailed notification as the authority for eligibility, stages, pattern, and syllabus. Treat the dedicated RRB notice page as the authority for later operational updates such as schedules, city intimation, e-call letters, rescheduling, answer keys, and results.

Do not treat social-media posts, coaching thumbnails, or old NTPC notifications as substitutes. A past notification can be useful for practice, but it must be clearly labelled by year and must never silently override CEN 07/2025.

2. CBT-1 pattern at a glance

According to paragraph 13.1 of the official detailed notification:

Component	Questions	Marks
General Awareness	40	40
Mathematics	30	30
General Intelligence and Reasoning	30	30
Total	100	100

• Standard duration: 90 minutes.
• Duration for candidates eligible to use a scribe: 120 minutes.
• Each question carries one mark.
• A wrong answer deducts one-third of a mark.
• The section-wise distribution is indicative; the actual paper may vary.
• CBT-1 is a screening stage. Normalized CBT-1 scores are used for shortlisting to CBT-2.

Score calculation

Use:

Net score = correct answers − (wrong answers ÷ 3)

Example: 75 correct, 15 wrong, and 10 unattempted gives:

75 − (15 ÷ 3) = 70 marks

Unattempted questions do not attract the stated wrong-answer penalty. This means an extra attempt is valuable only when your probability of being correct justifies the risk; blind guessing is not a sound strategy.

3. What the three sections cover

Mathematics

The notification lists Number System, Decimals, Fractions, LCM, HCF, Ratio and Proportion, Percentage, Mensuration, Time and Work, Time and Distance, Simple and Compound Interest, Profit and Loss, Elementary Algebra, Geometry and Trigonometry, and Elementary Statistics.

Study these as connected families. For example, ratio, percentage, profit-and-loss, and interest all depend on proportional reasoning. Build accuracy first, then speed.

General Intelligence and Reasoning

The official scope includes Analogies, Number and Alphabet Series, Coding-Decoding, Mathematical Operations, Similarities and Differences, Relationships, Analytical Reasoning, Syllogism, Jumbling, Venn Diagrams, Puzzles, Data Sufficiency, Statement–Conclusion, Courses of Action, Decision Making, Maps, and Graph Interpretation.

Do not memorize only puzzle templates. Learn what each question is testing: ordering, classification, implication, constraint tracking, or spatial interpretation.

General Awareness

This has the largest indicative share. The scope includes current events; sports; Indian art, culture, literature, monuments, history, and freedom struggle; geography; polity and governance; economy; environment; science and technology; basic computer knowledge; transport systems; public-sector organizations; and General Science/Life Science up to Class 10 CBSE level.

Separate this section into:

1. Evergreen foundations — history, geography, polity, economy basics, science, computers.
2. Time-sensitive updates — current events, appointments, awards, recent programmes, and developments.

Every time-sensitive fact needs a date and a reliable source.

4. A diagnostic-first study method

Start with one timed 100-question diagnostic. Do not use the score to judge yourself; use it to classify errors.

Error type	What it means	Correct response
Concept gap	You could not identify the rule or method	Learn the concept and solve untimed examples
Method gap	You knew the topic but chose an inefficient route	Compare methods and record the shortest reliable one
Calculation error	Your approach was sound but execution failed	Use written checkpoints and estimation
Reading error	You missed a condition, unit, or qualifier	Underline constraints before solving
Risk error	You guessed without enough elimination	Track confidence and apply a stopping rule
Recall decay	You had learned the fact but could not retrieve it	Use spaced revision and short retrieval quizzes

Your weekly plan should give more time to high-frequency weaknesses, not simply repeat your favourite subjects.

5. Practical seven-day foundation cycle

• Day 1: Timed diagnostic; create an error log.
• Day 2: Mathematics fundamentals plus 20 mixed questions.
• Day 3: Reasoning fundamentals plus 20 mixed questions.
• Day 4: Evergreen General Awareness plus a short current-affairs review.
• Day 5: Two weak-topic repair sessions; retest only those skills.
• Day 6: One timed sectional set for each of the three areas.
• Day 7: Full mixed mock, review every wrong and uncertain answer, then revise the next cycle.

A mock is incomplete until its errors have been reviewed. Record the concept, why the chosen option looked attractive, why it was wrong, and the rule that would prevent the same mistake.

6. Accuracy and attempt strategy

Track four numbers after every timed set:

• attempted questions;
• correct answers;
• wrong answers;
• time used.

Then calculate accuracy as correct ÷ attempted × 100 and net score using the official penalty. Compare two attempts only when question difficulty is reasonably similar.

Use a two-pass approach:

1. First pass: solve direct, high-confidence questions.
2. Second pass: return to questions requiring more steps or careful elimination.
3. Leave a question when further time is unlikely to improve your decision.

There is no universal “best” time split. Use mock evidence to set a personal allocation, while remembering that General Awareness has the largest indicative question count.

7. Evidence-safe current affairs

For each current-affairs note, store:

• the fact;
• the event date;
• the publication date;
• the primary or authoritative source;
• one line explaining why it belongs in the syllabus; and
• a review date.

If a fact changes, update the note rather than adding a contradictory duplicate. Never invent “previous-year questions.” Label reconstructed or practice questions as practice.

Check your understanding

1. How many questions are indicated for General Awareness in CBT-1? 40.
2. What is the standard CBT-1 duration? 90 minutes.
3. What is the penalty for nine wrong answers? 3 marks.
4. If you answer 60 correctly and 12 incorrectly, what is the net score? 56 marks.
5. Is the section-wise split guaranteed to be exact in the live paper? No; the notification calls it indicative.
6. Which source should you check for a rescheduled exam date? The dedicated official RRB notice page for CEN 07/2025.
