Hey! Sorry to say but chances are a bit rare in OBC category to get a government college at 433 marks according to the previous year knowledge however you should still not lose any hope. Sit for the counselling procedure, dont lose your hope till the last round..Sometimes the reverted seats from sc or st if not filled goes to the obc category.. You can also look for private college.. Good luck.. 

Hello,

Based upon your score in NEET 2019 and the previous year cutoff, chances are less for admission to Government Medical Colleges under any of the quotas. You may have chances in Private Colleges. Use NEET College Predictor to Check Your Chances in private colleges Based on Your NEET AIR
