Hey

After the implementation of NEET, the admission to all medical colleges are solely done on the basis of marks obtained by candidates in the entrance exam. As far your question is concerned, I don't think you have to register for the college as it will admit students on the basis of their performance in NEET entrance exam. The link to the full detailed information including, eligibility, fees, etc about the college is mentioned below,

Hope that helps.

Thank you.
