You have to mention whether or not you availed any reservation during MBBS admssion in Bengal. MCC considers a central list for OBC caste for NEET PG counselling while taking students under All India Quota or AIQ. If your caste is under the state list of OBC caste, you will be eligible for a reservation under the OBC quota in the state counselling if and only you apply for state quota seats in your state. So you can course avail the benefits of reservation under OBC in your state. You have to check whether or not your caste is involved in the West Bengal OBC list, if not you will be treated as a general category student for the AIQ seat and won't be able to avail any benefits of reservation. Through NEET PG cutoff, candidates who cleared the cut-off will be awarded entry to 50% All India Quota (AIQ), 50% state quota, all deemed/central universities, ESIC/AMFS colleges, and private institutes.
