No, you can't join IIST with your state marks.

MBA is the test of your attitude, aptitude and approach. The right combination of these three is necessary to get through.
Prowess- the most comprehensive program for MBA preparation.
Most students are attracted to management education at top business schools because of the high pay packages they get at the end of it. Sure, it is a brilliant career to pursue, but if your ultimate aim is to stuff your pockets, you might just cut a sorry figure in your future life or, for that matter, even in your Group Discussions or your Personal interviews.

Dear Candidate, your question is an open-ended one as how much marks you should get solely depends on your ambitions. As you are graduate from DU, FMS want you to get 99 percentile. With OBC-NC, you will need 97 percentile for IIM A/B/C and 95 percentile for later IIM's.
You can get calls from new IIM's at 90 percentile. The rest SP Jain calls you at 85 percentile.
All the Best!

I would suggest you to go with SJIBIT as its placements are around 99.89% as per NAAC and it has been graded 3.2 by the same. Overall, it is the best college.

You need to clear IIT-JEE Advance to get admission in IIST. In class 12th, you should have at least 20% marks in aggregate and at least 5% in each of the three subjects (Physics, chemistry and mathematics). All the best your future.
