You can't get a good cse college at this rank. Even if you take admission in some other college it would be just a waste of money. In that case I would suggest you to go for private colleges like Heritage Institute of Technology through management quota where you need to pay huge fees.

Other than cse branch you can consider different branches where admission is possible explore WBJEE CUTOFF to find exact options.

And if you dont want these colleges then try reappearing for the next year if you are not a dropper already.

Beat of luck.
