How to Calculate Your Score Using the IIT JAM Answer Key 2027

To calculate your expected score, you need both your IIT JAM 2027 response sheet (downloaded from the JOAPS portal) and the official answer key. Match your responses against the answer key question-by-question, then apply the marking scheme for each section.

• Download your response sheet from the JOAPS portal and open the answer key PDF for your test paper side by side.
• For Section A (MCQ): add +1 mark for each correct 1-mark question, and subtract –1/3 mark for each incorrect 1-mark question; add +2 marks for each correct 2-mark question, and subtract –2/3 mark for each incorrect 2-mark question.
• For Section B (MSQ): add +2 marks for a fully correct response (all correct options selected, no incorrect options); there is no negative marking and no partial marking for MSQ.
• For Section C (NAT): add +1 mark for each correct 1-mark question and +2 marks for each correct 2-mark question; there is no negative marking for NAT questions.
• Unattempted questions in any section carry zero marks.
• Add up the scores across all three sections to get your total expected score out of 100.

Note: Only the official IIT JAM Result 2027 will contain your final, verified score; self-calculated scores using the answer key are estimations only.
