Hi

Usually before covid-19 issues, it will happen around June in most of the colleges and universities of India. After filling the form applicants will be shortlisted based on the mars and other criteria. Then administration will put a merit list for admission with waiting list. If any applicant from merit list is rejecting the offer, it will go to the waiting list person. So check the official website of the respective college and contact them regarding essential information.

Hope it helps.
