The cutoffs change every year as it depends on various factors. If we go through the cutoffs of last few years' then we can see that the b.pharm seats of Jadavpur University get filled within 1000 rank in WBJEE. After Round 3 of counselling, the last rank to get selected in Jadavpur University stays around 1100. So it seems you have very less chances there. There are only 2 or 3 government pharmacy colleges that accept WBJEE Score. However, you can go for Institute of Pharmacy, Jalpaiguri as the closing rank for B.Pharm OBC B category lies around 4221 rank. So you have fair chances there and it's a government pharmacy college. Apart from this, you can expect almost all the private pharmacy colleges at this rank like Guru Nanak Institute of Pharmaceutical Science and Technology, Techno India University etc.
