Hello dear,

With respect to last year data, 300 marks may fetch you all india rank around 2.5 lakhs.

But the cut off for B-category seats in AP was 2.27 lakhs (320-325 marks) which was in VMC medical college, Kurnool.

But you have chances to get a B-category dental seat.

Hope you found this helpful.

All the best!
