In general, we do NOT recommend repeating courses unless it is necessary (below a C). In reviewing an application, the admissions officers and committee examine GPA, course load, withdrawals and repeats. Reduced course load, course repeats or withdrawals can adversely affect an applicant's ranking. When planning your pre-pharmacy curriculum, determine your readiness to fully engage in the course requirements and learning strategies before each semester begins.
Improvements in GPA are best pursued by taking higher level courses, as opposed to repeating courses already taken.
