Hello,

Joint Admission test for Masters is a common admission test conducted every year for admission into Master of Science and other post-graduate science programs at Indian Institutes of Technology, Indian Institute of Science and National Institutes of Technology, organized by alternating institutes every year.

No, class 10th and 12th marks do not matter in the admission kf IIT for MSC ACOURSE AFTER IIT JAM exam. The only eligibility is that ypu should have a minimum of 55% in your Bachelor's course. It differs in case of candidates from SC and ST.

I hope this helps,

All the best
