RRB NTPC UG 2026 Exam Pattern and Marking Scheme: How to Calculate CBT 1 Expected Score

After downloading the RRB NTPC UG CBT 1 Response Sheet 2026, candidates can calculate their estimated score using the official marking scheme. The CBT 1 examination comprised 100 objective-type questions to be answered in 90 minutes, divided into three sections - Mathematics, General Intelligence and Reasoning, and General Awareness. Each correct answer carries 1 mark, and there is a negative marking of 1/3rd mark (0.33 marks) deducted for every incorrect answer. No marks are deducted for unanswered questions.

Score Calculation Formula: Total Score = (Number of Correct Answers × 1) − (Number of Wrong Answers × 0.33)

For example, if a candidate answered 80 questions correctly and 15 incorrectly, the estimated score would be: (80 × 1) − (15 × 0.33) = 80 − 4.95 = 75.05 marks.
