Hello aspirant

According to the previous year cut off, an OBC category candidate scored 539 marks to fetch a seat in government medical colleges in Tamil Nadu, which is your domicile state.

When we look at the cut off's of other states too, they go as stated under, for OBC category-

Maharashtra- 554

Punjab- 550

Madhya Pradesh- 545

West Bengal- 574

Rajasthan- 630

Uttar Pradesh- 597

Bihar- 606

So you can see you have very low chances of getting into a government college, or even securing government quota in private colleges. However, you do have chances of getting the following private and deemed colleges-

Heritage Institute of Medical Sciences, Varanasi- 397

Hind Medical College, Sitapur- 398

Muzzafarnagar Medical College- 398

BLDE University, Bijapur- 367
