Hi there,
If you belong to General Category, then with 30272 rank in CRL it would be difficult for you to secure any core branch like CSE, IT or ECE in a good NIT. But you can opt for branches like Mechanical, EEE or ICE at some good NITs.
In SRMJEE you can easily get SRM Chennai campus.
From VITEEE you can get any branch in any campus of VIT except for CSE at VIT Vellore.

So, If you have a hard desire to go for CSE or IT, then you should choose IT at VIT Vellore or CSE at VIT Ramapuramor else you can go for Mechanical at the NITs.

Hope it would help.
