Hello,
Actually it's totally depends on your previous college as well as your new college. Because no college wants to leave their students in current year. So yoi cam talk to the college authorities and principle also. Then listen what they are saying. But i don't think they will agree but if you know how to convince them then it's okay.
And another thing if you get new college through giving NEET examination again then you can click your previous college to leave you and you have to pay some leaving amount also to your previous college.
All the best.
