You have less chances to get government colleges.

Through, JEE Main you can apply for private colleges. You can get 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.
