Dear Nimisha, each Medical college has its own criteria as when you should fill in the application. For example, CMC Vellore releases its online application well before NEET results are announced. You have to fill in the basic details and once the results have been announced, you need to fill in just the NEET score. Your application will be based on their cut offs. On the other hand, AFMC releases uts online application forms after NEET results have been announced. AFMC announces its own cutoffs for its college and opens the registration process for valid candidates. So it is important to check the criteria of the college that you want to join.
