Hi, Assuming you are talking about general category, you have less/no chances in CS branch.

Also you will have to apply in other private state colleges like UP, Haryana, Rajasthan etc.
There you might stand chances in some of the branches apart from top ones like CS, Mechanical.

Based on your marks you have less chances in NITs

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.
