Hello can I get any dnb orthopedics or dnb surgery in a good college with a rank of 10857 (obc)
The chances are less to get All India Quota seats for Orthopedics or General Surgery with this rank. If you want to check your other admission possibility in All India Quota seats, Central University & Deemed universities, You can use NEET PG College Predictor tool.
