CSIR NET Answer Key 2026: How to Calculate Scores

Candidates can use the provisional answer key to estimate their probable scores before the official result is declared. The key step is to match responses with the correct answers and apply the marking scheme for each section. Since the marking scheme differs by subject and part, using the correct values is important for an accurate estimate.

• Compare each attempted response against the provisional answer key for the correct answer.

• Add marks for each correct answer based on the subject-specific marking scheme for Parts A, B, and C.

• Deduct negative marks for each incorrect answer, based on the penalty applicable for that subject and part.

• Questions left unattempted carry zero marks and should not be included in either the positive or negative tally.

• If a question is found incorrect after review, full marks are awarded to all candidates who attempted it.

• If multiple options are declared correct after expert review, full marks are awarded to candidates who selected any of the correct options. Note: Part C of Mathematical Sciences follows separate rules in this regard.

• Total the raw marks from Parts A, B, and C to get the overall raw score. Note that no separate cutoffs exist for individual parts.

• The raw scores are later normalised across exam shifts before the final result is prepared. The normalised score may differ from the raw score.

For a quick reference, the marking scheme across all subjects is summarised below as per the CSIR NET Exam Pattern 2026:
