Hi

Well you have to admit you have very low marks. You have low chances to get any Government College. But with ST Category Quota seats, you might get these Government colleges under 15% All India Quota-

Patna Dental College & Hospital, Patna (low chance).

HP Government Dental College & Hospital, Shimla (low chance).

You can always check the same about NEET 2019 cut off for government colleges in a greater detail through this link: https://medicine.careers360.com/articles/neet-cut-off-for-government-colleges .

Best of Luck.

Hope this helps.

Cheers!
