Computer Science and Engineering Eligibility

Hello Soumyadip, Heritage is one of the top private engineering colleges of West Bengal, hence the cutoff is low. In 2018, after 3rd round the opening WBJEE rank was 1018 and closing rank was 4130 for CSE. I guess it went upto 5k in the spot counseling (mop up) round.
So you have to get a rank under 4k to be on the safe side.

There are many options like BBA, B.Com, BA in sports psychology and so on. Please clarify which option you want to choose.
There are many universities like:
Amity University
Jagannath University
IGNOU
Delhi University
NMIMS and so on.

Here are some top engineering colleges in Bangalore:
1. MS Ramaiah Institute of Technology
2. Jain University College of Engineering
3. Viswesvaraya College of Engineering
4. RV College of Engineering
5. International Institute of Information Technology, etc.

Hello Soumya,
You can get admission in IEM. You will probably not get CSE but can get other branches like IT, ECE, EEE, EE or ME. In IEM only 10% seats are allotted for admission through JEE Main. So, it depends on luck.

Yes, you can get good state label college as private colleges at this Marks, but very less chance fir NIT.

If you are general category, then it is not possible but if you belongs to SC/ST, then you are eligible for NITs.

You can get CSE due to reservation quota your SC category rank is pretty good.

You may get CSE, I this college. Apply for it. Minimum 40% in class 12th aggregate is required for eligibility and admission depends on cutoff.

You may try for it. There might be chance that you get CSE in LNMIIT, but you can also apply for CCE, which also has good placement record and it also contain more than half of the CSE Syllabus.
