Hi Garima 

This is RitikA

The marking scheme of ISER exam is that for every correct answer you will be awarded 3 marks and for every incorrect answer 1 marks will be deducted.This means almost 33.4%will deducted for every wrong attempt

Hope my answer helped you

Thank you

Hey Garima Dubey,

IISER of the Indian Institute of Science, Education and Research will conduct the IISER 2019 Aptitude Test in computer based test mode only. In the test, 3 marks are awarded for every correct answer. There is negative marking. 1 mark will be deducted for every wrong attempt.

Good luck.
