This initial stage of the examination was conducted by the Railway Recruitment Board from May 7, 2026, to June 20, 2026. Candidates can now access their individual response sheets, which display their recorded answers alongside the officially correct answers, enabling self-evaluation of their performance.

Important Dates for Answer Key and Objections

The CBT 1 exam commenced on May 7, 2026, and concluded on June 20, 2026. The provisional Answer Key was made available on June 27, 2026, at 7:00 PM, simultaneously opening the objection window. Candidates have until July 5, 2026, at 11:55 PM to submit any challenges. The expected result for CBT 1 is August 2026, with the CBT 2 exam tentatively scheduled for September 17, 2026.

Objection Process and Fee Structure

To challenge any question in the provisional answer key, candidates must pay an objection fee of Rs.50 per question, in addition to applicable bank charges. This fee can be paid conveniently using Debit Card, Credit Card, UPI, or Net Banking. It is important to note that the fee is refundable only if the objection raised by the candidate is accepted as valid by the Railway Recruitment Board after review. The decision of RRBs on all objections will be final and binding.

Eligibility, Vacancies, and Selection Process

The RRB NTPC Undergraduate recruitment targets candidates who have passed 12th grade, with specific qualifications for posts like Commercial cum Ticket Clerk, Junior Clerk cum Typist, Accounts Clerk cum Typist, and Trains Clerk detailed in the official notification. A total of 3058 vacancies are available across these posts. The selection process primarily involves two Computer-Based Tests: CBT 1 (already conducted) and CBT 2, tentatively scheduled for September 17, 2026.

Calculating Your CBT 1 Score

Candidates can estimate their CBT 1 score using a clear marking scheme. For every correct answer, +1 mark is awarded. Conversely, 0.33 marks (one-third) are deducted for each incorrect answer, while unattempted questions receive 0 marks. The estimated score can be calculated using the formula: (Number of Correct Answers × 1) – (Number of Incorrect Answers × 0.33). This calculation provides a preliminary idea of performance before the official results.
