Hello,
Yes, you are eligible for MSc programs in IITs if you meet the following criteria:
Aggregate Percentage: Most IITs require at least 55% (for General/OBC) or 50% (for SC/ST/PwD) in your qualifying degree. Since your aggregate is more than 70%, you meet this criterion.
Backlogs: IITs generally allow students who have cleared all backlogs before applying. Since you have already cleared your backlog, it should not be an issue.
Entrance Exam: Admission to MSc programs in IITs is primarily through IIT JAM (Joint Admission Test for MSc). You need to qualify for JAM and secure a good rank.
