Hi Sayan, you can take GRE, it is advisable you undertake a coaching class as you didn't have mathematics. For your information, you need to take GRE if you are applying to universities particularly in US and Canada. So, before you prepare for the application check the application requirements and decide where to apply. Hope it helps.

Hi Deepika
Yes of course you can pursue B.Pharm after B.Sc Botany

B.Sc (Botany) will be more helpful as it would be useful to select as an optional for the IAS Exam (Mains).it would be also helpful to choose your career as a teacher/lecturer in that subject. .
