Steps to Calculate GATE 2025 Scores

Candidates can check their probable GATE exam scores in the following way -

  • Determine the total number of correct responses and allot points or scores to determine the final score.
  • Candidates must calculate the marks deducted for incorrect answers. (Negative marking is only applicable for MCQs and MSQs). There is no negative marking for Numerical-Based Questions. 

The mathematical formula to calculate the GATE 2025 scores is as follows -

Total Marks = Total marks secured for the correct response - Negative marks for the wrong response

Q:   What is the meaning of "marks to all" in GATE official answer key?

A:

In the GATE official answer key, the “Marks to all” implies that everyone will get the marks for the specific question, regardless of whether they have attempted. This can also be used to calculate the overall score for the test taker. Further, as per some experts, generally after the exam, a panel of experts, which is different from the paper-setting team, will be formed. Then, they will review all the solutions to a particular paper. In some cases, a panel of experts may not agree with the solution or response given by the paper-setting team. Therefore, in such cases, there will be discrepancies between both teams, and so they will mark those questions as MTA, which means marks to all. However, the MTA will not affect the ranking of the candidates. Read More: https://www.shiksha.com/engineering/gate-exam-answer-key.
