Hii sir I got 421 marks in neet 2019 and my category is RBA sir can I have a chance to get seat in gmc

RBA falls under General Category. However, when you fill in the Cpunselling application form, you declare your RBA Status. Going by that, in 2018, under State Quota, 440 marks secured a seat in Sher-e-Kashmir Institute of Medical Sciences. With new 4 colleges coming up, you have a decent chance with 421 marks. Having said that, cut offs change every year and are dependant on various factors like no.of seats availble, no.of candidates appearing for the exam, top NEET score and difficulty of the exam. You can check the cut offs of each college at:
