Sir, i am from gujarat and I have cleared my gseb board exam 2019 and have 68.14% in that and will got about 300 in NEET {categorie OBC}

Let me first tell you that the determining the rank is difficult because it depends on the difficulty of the exam and also how others attempt their paper. Still at 300 marks your ranking can fetch you colleges like PRMED(Parul Institute of Medical science and research),rmed(pdu medical college rakjot)  and dental in narsinhabhai dental college, college of dental sciences and research (ahmedabad), dharamsinh desai Institute of dental sciences, gandhinagar
