How to Calculate Your Score Using RRB NTPC UG Answer Key 2026

Answer Type	Marks
Correct Answer	+1 Mark
Incorrect Answer	-0.33 Marks (1/3rd negative marking)
Unattempted Question	0 Marks

Once you have downloaded the provisional answer key, you can estimate your expected CBT 1 score by using the official marking scheme. The RRB NTPC UG exam follows a negative marking pattern, so candidates should account for wrong answers while calculating their scores.
Score Calculation Formula
Estimated Score = (Number of Correct Answers × 1) - (Number of Incorrect 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.
