 Students who pursue the IB diploma must take six subjects: one each from Groups 1 – 5, and either one from Group 6 or a permitted substitute from one of the other groups, as described below. Three or four subjects must be taken at Higher level (HL) and the rest at Standard level (SL). The IB recommends a minimum of 240 hours of instructional time for HL courses and 150 hours for SL courses.
