RRB NTPC Undergraduate Answer Key 2026 Out: Download CBT 1 Response Sheet PDF, Objection Link Active Till July 5

The RRB NTPC UG CBT 1 exam was conducted for 90 minutes (120 minutes for PwD candidates). The paper comprised three sections: Mathematics, General Intelligence, and General Awareness. Each question carries 1 mark, and there is a negative marking of 1/3rd mark for every incorrect answer. No marks are deducted for unattempted questions.

Score calculation formula:

Estimated Score = (Total Correct Answers × 1) − (Total Incorrect Answers × 0.33)

Example: If you attempted 90 questions, answered 72 correctly, and got 18 wrong — your estimated raw score = 72 − (18 × 0.33) = 72 − 5.94 = 66.06

Based on past RRB NTPC cut-off trends and the moderate difficulty level reported for the 2026 exam, candidates scoring in the 75–90 marks range (normalised) are generally considered in a safe zone for CBT 2 shortlisting. However, candidates should note that the board applies normalisation to account for difficulty variation across different exam shifts and dates.
