I hope you have given wbjee in 2018. But whatever be the case you can not take admission in degree level pharmacy courses at other colleges through GMR(general merit rank).Pharmacy  at Jadavpur University is applicable through GMR only.

You will have to go through PMR(pharmacy merit rank) for other colleges.This rank is prepared through combined paper of Physics and Chemistry. Separate reserved  categories are also applicalbe for counselling.
