There is no direct entry from high school into College of Pharmacy programs. Students must first complete a year of University “Preparatory Year” and take courses in English, Biochemistry, Learning skills, Computer skills, Genetics and Cell physiology. Admission to the program is competitive based on a student's performance in the required courses, their intent and their overall academic record (GPA).
The application to join is done through the University Admission and Registration Deanship.
