Hello, 

You can apply for the counselling for admission in medical courses through All India Quota counselling and State Quota counselling. Both these procedures are conducted by different authorities separately and at different time. You can apply for both these procedures of counselling. 

The cut off marks for All India Quota usually are in the range

550 and above for Open Category

450 and above for Reserved Category

The cut off marks for State quota will vary from state to state and also on the number of students registering for the state quota counselling. 

However, the general range of cut off is 

500 and above for General Category

400 and above for Reserved Category

The cut off score for reserved category may fall in less than 400 marks range but only in a few states. 

I assume you belong to Open Category as you have not mentioned your category. Therefore, your chances of admission for MBBS are a little less in All India Quota and state quota. Please note that, the cut off marks vary from state to state and therefore, your chances of admission will also change accordingly.

Hope this helps.

Good Luck.
