Having a score of 477 in NEET 2020, in spite of having certain categorical advantage, I believe you have bleak chances in securing an MBBS Seat in a Government Medical College. However do try for State Medical Colleges, through State Counselling and keep an eye on the State Medical Counselling Procedure and Dates. Besides MBBS, you may have fair chances in securing a seat in BDS, BHMS or BAMS, of course depends on your preference.

I would suggest you to consider a drop ,since you are one of the luckiest batches, with NEET 2021 just months away in April/May next year, work hard , refine your knowledge and secure a seat in a Top Medical College of your choice. Ive seen students like you securing in range 450-500 in first try and confirm increasing it to minimum 580-630 range next year.
