dear nabesh negi,

with the score you have got with ST category, you have slim to no chance to secure a government medical college either via all india quota or state quota since the cut off for ST category was at least more than 350 previous year and yes the cut off fluctuates each year and hence it has been predicted that the cut off will increase by 25 marks this year. i am adding the links below for you to check and confirm the above stats i have mentioned.
