Once the counselling dates are out (which will be given by the CCSU, Meerut), you will have to download, fill, and submit the registration form for MBBS/BDS counselling. Once the registration process is complete, the university will release a merit list (probably on its website) on which you will find your name, marks, and rank along with the date and other instructions of your counselling. You will have to attend the counselling in person or online (it can be conducted in either way) in order to get a seat.
