Bro which  colleges did you get ? And which college offers you cse

You have less chances based on your rank in other state quota.

Can you tell me your home state?

You can get good private college in other states like: Haryana, UP, West Bengal, Punjab, Rajasthan, Maharashtra. Most of the states have reservation for other state students in private colleges based on JEE Main score/rank. You need to apply separately for them.
