Hi,

IIT JAM exam conducted for UG graduates to get M.Sc. admission in top IITs, IISc, etc. So this exam only consider UG marks and there are no such requirements for HS marks, they don't have any criteria for HS marks.

JAM appearing candidates requires to have at least 55% in their UG for General & OBC category (50% for other categories). As per IIT JAM qualification criteria, candidates who have either appeared or are going to appear in the final semester examination of their bachelor’s degree are also eligible to appear in this exam.

I suggest checking all other qualifying criteria and subjects you are willing to appear in IIT JAM exam on their official website before appearing to exam.

All the best!
