Dear Reshma, well one particular website shows that the applications have been closed. However that article has been dated November 2018. So they are tentative dates. Ideally Government colleges dont release the online applications before NEET results. Once NEET results have been announced along with the final merit list, colleges will release their cut offs and open their online registration portals for qualified students to register and fill in the application form online. So the applications havn't started yet. Please keep an eye on the official website from the last week of May.
