You must have passed B.Sc with 45% marks and passed XII standard with math and also clearing UPSEE exam are the eligibility criteria for UPSEE counselling. If you do not clear UPSEE test, you will be take admission in private college with management quota.

You must be B.Sc passed with 45% marks and passed XII standard with Maths and then you will be eligible for UPSEE counselling.

You have less chances for CS but you can take IT branch in GL Bajaj.

You will tell for counselor during document verification. And also call helpline number. I think there is no problem.

I would advise you to join some designing course so that you can start with something and improve your skills.

By going through the last years' placements statistics, cutoffs and ranking, VNIT comes on top. VNIT is better in every aspect. I will suggest you to go for VNIT.
All the best.

UPES is good but you'll have to check whether UPES takes admission on the basis of 12th standard marks.

You have a good chance of getting admission in a government college.
