How to Calculate Score Using GATE answer key 2024?

Using the gate 2024 exam answer key, candidates can calculate probable scores following the below steps:

  • Calculate the total number of correct answers and allocate marks accordingly and then calculate the overall marks.
  • The candidate has to tally the total negative marks for wrong attempts. (Only Multiple Choice Questions (MCQs) will have negative markings. There will be no negative marking for NAT questions). So the calculation goes:
  • MCQ Marks: Total marks (1 mark) + Total marks (2 marks).
  • Total marks (1 mark) = 1 x no. of correct attempts – 1/3 x no. of wrong attempts.
  • Total marks (2 marks) = 2 x the number of correct attempts – 2/3 x the number of wrong attempts.
  • NAT Marks: Total marks (1 mark) + Total marks (2 marks).

Formula: Total marks = Total marks secured for correct response – Negative marks for wrong response.
