Congratulations on qualifying NEET 2020.

I believe at a score of 587 besides having the OBC Advantage, if not Delhi, you can easily get yourself alloted any good State Government Medical College in Bihar, under Home State Quota. Some of the best Medical Institutes in Bihar being PMCH Patna, Nalanda Medical College, Darbhanga Medical College, ANMMCH Gaya, JNMCH Bhagalpur as well as Vardhaman Institute of Medical Sciences. These Medical colleges in Bihar have excellent Faculty, Infrastructure and Hospital Facilities. Do keep an eye on the Government and State Medical Counselling Dates and Procedure.
