5. How to Calculate Your Expected CBT-1 Score

Formula: Raw Score = (Correct Answers × 1) − (Wrong Answers × ⅓)

CBT-1 Pattern: 100 questions | 100 marks | 90 minutes | Negative marking: 1/3rd per wrong answer

Example	Correct	Wrong	Unattempted	Score
1	72	18	10	(72×1) − (18×0.333) = 66.00 marks
2	80	15	5	(80×1) − (15×0.333) = 75.00 marks
3	60	30	10	(60×1) − (30×0.333) = 50.00 marks

Note: Unattempted questions carry zero marks and zero penalty. Compare your recorded responses (from the response sheet) with the provisional key — not from memory.

10. FAQs

#	Question	Answer
1	The answer key portal shows an error when I try to log in. What should I do?	The portal experiences high traffic right after release. Try later (evening/early morning), try a different browser, clear cache/cookies, and ensure your Registration Number has no spaces. Don’t wait until 5 July 2026 to check — raise objections well in advance.
2	My recorded response differs from what I remember choosing. What does that mean?	The recorded response captured by the computer system at exam time is considered final. Your score is calculated based on recorded responses only, not what you believe you selected. Objections apply only to the answer key answers, not to recorded responses.
3	I raised an objection. When and how will I know if it was accepted?	RRB reviews all objections and prepares a Final Answer Key after the window closes on 5 July 2026, published on the official portal. Objection fees are automatically refunded if accepted. RRB does not send individual notifications — compare the Provisional and Final keys to spot changes.
4	Are CBT-1 marks added to the final merit list?	No. CBT-1 marks are used only for shortlisting candidates for CBT-2. Final merit and selection is based entirely on CBT-2 marks (scheduled 17 September 2026).
5	What is a safe score in CBT-1 2026 to qualify for CBT-2?	Tentative estimates: General/UR: 75–82 marks | OBC (NCL): 70–77 marks | SC: 60–68 marks | ST: 55–65 marks. These are estimates only, not official cutoffs — actual cutoffs depend on difficulty level, normalisation, and category-wise applications.
6	I appeared in multiple shifts. Will marks be normalised?	Yes — RRB uses the Equi-Percentile Normalisation Method to ensure fairness across shifts/dates. The normalised score (not raw score) is used for CBT-2 shortlisting.
7	What happens after CBT-2 for RRB NTPC UG posts?	Junior Clerk & Accounts Clerk: Typing Skill Test (30 WPM English or 25 WPM Hindi, qualifying). Commercial cum Ticket Clerk: Computer Based Aptitude Test (qualifying). Trains Clerk: no additional test — straight to Document Verification. Final merit is based on CBT-2 marks only, followed by Document Verification and Medical Examination.
