What is IISER Response Sheet?
The IISER response sheet is a digital record of the answers you selected during the IAT 2026 exam. It lists each question along with the option you chose. The response sheet does not tell you whether your answer was right or wrong. It only confirms what you marked on the computer screen.
Many students confuse the response sheet with the answer key. The two are completely different. The answer key gives the official correct option for every question. The response sheet gives only your recorded responses. You need both to calculate your score.
The IISER 2026 response sheet shows your roll number, application number, question paper, and your marked option for each of the 60 questions.

How to Use Response Sheet with Answer Key
The response sheet alone cannot tell you your score. You must compare it with the answer key. Here is the step-by-step process.
- Download both your response sheet and the IAT 2026 answer key.
- Open both files side by side, question by question.
- For each question, compare your marked option with the correct option.
- Mark each answer as correct, incorrect, or unattempted.
- Count your total correct answers and total wrong answers.
- Apply the official marking scheme to calculate your expected score.
Always use the final answer key with your response sheet, not the provisional one. The provisional key may change after objections. Your score is most accurate once the final key is out.
How to Calculate Score from Response Sheet
The IAT 2026 follows a simple marking scheme. You get 4 marks for every correct answer. You lose 1 mark for every wrong answer. Unattempted questions carry no marks. The paper has 60 questions for a total of 240 marks.
Use this formula to find your expected score:
Expected Score = (Correct answers × 4) − (Wrong answers × 1)
Worked example: Suppose you answered 40 questions correctly and 10 questions wrongly, and left 10 unattempted.
- Marks from correct answers = 40 × 4 = 160
- Marks lost from wrong answers = 10 × 1 = 10
- Expected score = 160 − 10 = 150 out of 240
The 10 unattempted questions add nothing and take nothing away. Be honest while counting wrong answers, since negative marking affects your final score.
| Response Type | Marks Awarded |
|---|---|
| Correct answer | +4 marks |
| Wrong answer | −1 mark |
| Unattempted question | 0 marks |
| Total questions | 60 |
| Total marks | 240 |
