You havent mentioned your Category. Neverthless, in 2019 under State Quota the cut offs for KGMC under various Categories have been as follows:

General Category: 637

OBC: 629

SC: 528

ST: 362

Now cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam. For 2020, if you want a seat in this college, you should aim for atleast 30-45 marks more than mentioned here.
