Dear Shubha, we do not have 2019 data yet. However, in 2018 under All India Quota, under SC Category 560 marks secured a seat in GMCH. In 2017, the cut off was 483. Now as iti is visible, cut offs change every year and are dependant on various factors such as no.of Candidates appearing for the exam, no.of candidates qualified, top NEET score and difficulty of the exam. So if your target college is GMCH, you should aim at atleast 650.
