Hello Abhishek,
As per your marks in JEE Mains, you will get good branches in top NITs, however admission in Jadavpur University and VJTI is done via WBJEE and MHCET respectively not via JEE Mains.

You are eligible to seek admission in MCA on completion of B.Sc maths degree.

The JEE score is valid in most of the colg. And is the creteria for the merit list and cutoffs. Do visit the official websites of the institutes for percise and bonafide information is my suggestion.

You can see the percentage distribution of reservation for different categories and then calculate the number of seats depending on the intake capacity of the branch.
Regards.
All the best.

All core engineering branches have a decent cut-off. You can expect it to be around 95 for open category.

This course is not available in VJTI.

Yes. You can. Score matters. All the best.

Good chance, but it is difficult to be sure.
