Hii Mayank!
For admissions in Pharmacy course in general, across India, the eligibility criteria states that the candidate must have passed class 12th in PCB subject combination with atleast 50% marks. To get into one of the colleges providing the course, you need to give the entrance examination; either at state or at national level. Some of the exams are GPAT, IPU CET, MHT CET, WBJEE, EAMCET etc., You may visit the official Websites of the exams and get more information.
Hope this helps.
Good luck!
