- The numerical questions have no negative marking.
- GATE Score = Marks obtained for MCQs + Marks obtained for NAT questions
- MCQ Marks: Total marks (1 marks) + Total marks (2 marks)
- Total marks (1 marks) = 1 x number of correct answers – 1/3 x number of wrong answers
- Total marks (2 marks) = 2 x number of correct answers – 2/3 x number of wrong answers
- NAT Marks: Total marks (1 marks) + Total marks (2 marks)
