+ 3 marks for every correct response
– 1 mark for each incorrect response
0 marks for unattempted responses
(3 × Number of correct responses) – (1 × number of incorrect responses) = Probable Score in IAT
How to Calculate Score Using IISER Aptitude Test Answer Key?
Candidates have to follow the steps mentioned below to calculate the IISER Aptitude Test score.
Step 1 – Calculate the number of correct and incorrect responses using the IAT answer key, response sheet and question paper
Step 2 – Multiply the number of correct responses with 3
Step 3 – Multiply the number of incorrect responses with 1
Step 4 – Subtract the total marks of wrong answers from the total marks of right answers
The outcome will be your probable IISER Aptitude Test score
Example – For instance, out of the total 60 questions, you were able to answer 40 questions correctly, 15 questions were incorrectly marked and the remaining 5 questions were left unattempted. In such a case, the calculation will be done as follows:
Marks scored from 40 correct responses = 120 (40×3)
Marks deducted for incorrect responses = 15 (15×1)
- Marks for 5 unattempted questions = 0
You have to subtract 15 from 120. Hence, your IAT score would be 105 marks.
