You havent mentioned your Category. Neverhless, in 2018, under State Quota, the cut offs for BJ Medical College for various Categories have been as follows:
General Category: 557
SC: 440
ST:332
SE: 488
Now this is 2018 data. 2019 details are yet to be released as the counselling is yet to be completed for all rounds.

Now cut offs change every year and are dependant on various factors like no.of candidates appearing for the exam, no.of candidates qualified, top NEET score and difficulty of the exam.
