hi tanmoy (I assume it is NEET, you havent mentioned the exam)

be proud of your sister, she got a good rank and mark.

with her mark, there are some possibilities of getting a medical college only if there is vacancy. because they expect more marks from obc. so, you have to try your luck.

we cant predict the cutoff as it changes every year. so just apply and see. i wish she gets a seat.

WB has less seats. that is the problem. but nothing wrong in trying. so shoot your shot. apply as soon as possible.

the below link will help you choose best colleges based on your preferences.
