The most logical choice is to go to a University and take general courses for the first couple of years, including science and pre-pharmacy courses. These courses will prepare you for the admissions tests you will have to take to get into a pharmacy college.
After taking some of the basic courses, you will strive to get a B.S. degree in health pharmacy. This can vary in time, but typically you can get a degree in about five years or a Doctor degree in health pharmacy in about six years. Part of the five or six years of school should include time spent in pre-pharmacy course work.
