It is most important that you research the pre-pharmacy requirements of the schools that interest you. The American Association of Colleges of Pharmacy maintains the Pharmacy School Admissions Requirement (PSAR) which provides the admission requirements by individual schools and detailed information of each school.
Pharmacy programs generally require the following undergraduate coursework. Some schools may have additional requirements. Again it is important to check the requirements of each school you are considering to make sure you meet the course requirements.
