Hello, 101 marks is a low score. The cut off marks for open category is around 450-500 and above marks in state counselling and All India Quota counselling respectively. 

Chances of admission are very less. You can drop a year and study hard to get a good score in NEET 2020 and get admission in MBBS course. Or you can try for admission through management quota which will require lots of fees and donation.

I suggest you to take a drop if you desperately want to get admission into MBBS course in a good college without excess amount of fees and donation. 

Hope this helps.

Good Luck.
