Jahnavi, it depends on the State you belong to. You haven't mentioned the State you belong to. Neverthless, in States like Maharashtra, admission to B.P.Th is based on your NEET score. But in States like Telangana and AP, admissions to BPT are made on the basis of marks scored in your 12th. The respective Universities will open the registration process for B.P.T admissions and the merit list is prepared on the basis of Candidate's Category and marks scored in the 12th. Seats are allotted on the basis of merit and preference.
