CSIR-UGC NET: How To Calculate Scores Using Answer Key

CSIR-UGC NET scores are calculated by matching responses with the provisional answer key, adding marks for correct answers and deducting negatives. Marks are awarded for corrected or multiple-correct questions as applicable. Final raw scores from all parts are combined and later normalized across shifts before result preparation.

  • The provisional answer key is released on the CSIR NET website for candidates to compare their responses.
  • Marks for correct answers must be added according to the subject-wise marking scheme for Parts A, B, and C.
  • Negative marks must be deducted wherever the subject’s marking rules specify a penalty for wrong answers.
  • If a question is declared incorrect, full marks are awarded only to candidates who attempted that question.
  • If multiple options are found correct after expert review, full marks are awarded to candidates who selected any of the correct options (except Part C of Mathematical Sciences, which follows separate rules).
  • Total raw marks are calculated by combining scores from Part A, Part B, and Part C since no separate cutoffs exist for individual parts.
  • The raw scores are later normalized across shifts before the final result is prepared.
