Hey there, you have not mentioned the exam , so i am assuming it to be JEE. It depends upon your category and home state quota.

if you belong to general category, then it is difficult for you to get cs in any govt college whereas you can get other branches like ece, or ee.

if your category is SC/ST/OBC/PWD then chances are likely for you t ge cs in state funded colleges or NITs. here are few links to help.
