SRM Institute of Science and Technology, Kattankulathur

Go for counselling. It will give you a much clear idea.

Go for SRM University with that rank. It's surely gonna help.

A main campus is always better than an affiliated campus. SRM and VIT are no doubt one of the best private institutes in India. In my opinion SRM Chennai (main KTR campus) is better than VIT Bhopal. And with this rank, it would be easy for you to get in SRM.
All the best!

This year, SRM has changed its admissions criteria, they have fixed the fee for a range of 10,000 I.e. each set of 10,000 will have the same fee e.g. 1-10,000 has a different fee, next 10,001-20,000 have different fee structure and the fees increases after each set of 10,000. So, you can get computer science in the main campus, but it will be very costly.

You have scored a pretty good rank in SRMJEE. With this rank you can get any branch at any campus. Just your fee category will differ. It's upto your interest well, but I'll personally suggest that do go with the KTR campus.
