DP students must choose one course from each of five subject groups delivering a breadth of knowledge and understanding in language and literature, individuals and societies, the sciences and mathematics. Furthermore, students must also choose either an arts course from the arts group or a second course from one of the other subject groups. DP courses can be taken at higher level (HL) or standard level (SL). At least three, and not more than four, are taken at HL (240 teaching hours), while the remaining courses are taken at SL (150 teaching hours). SL courses ensure students are exposed to a range of disciplines that they might otherwise opt out of, and HL courses allow students to spend more time with subjects they are more interested in by exploring options in addition to the SL core curriculum. In this sense, all DP courses, regardless of whether they are SL or HL, are integral to the programme. Students can study and take examinations in English, French or Spanish. Two courses are classified as interdisciplinary, meaning that they satisfy the requirements of more than one subject group.
• Literature and performance (studies in language and literature subject group and the arts subject group)
• Environmental systems and societies (individuals and societies subject group and sciences subject group)
