Hi

As you have mentioned that your rank is around 300k, you have very low chances to get any seat in any good colleges through JoSAA. You cannot get Government Colleges. But you can always check your chances using our Careers360 College Predictor Tool to have a fair idea which college or branch you can get according to your profile.
