The International University of Beirut has a semester based academic calendar. The current semesters are fall, spring, and summer. The fall and spring semester consists of a 15 week academic period whereby a student of academic good standing can register a maximum of 18 credits maximum per each semester. Whereas summer semester consists of 6 weeks and a student can take maximum 8 credits. Only engineering students have an extended summer semester that consists of 10 weeks with maximum 15 credits per extended summer.

Each semester the add/drop period begins on the first day of classes. BIU students generally sign up for courses during the registration period before the start of each academic semester. However, you may sometimes want to change your schedule--by adding a course you are not yet signed up for or by dropping a course in which you are enrolled. At the end of each semester final examinations take place. The exams vary in timing and days and may be at a different time from the registered course
