Group 6 subjects are considered electives, thus an IB Diploma candidate may substitute a variety of courses from other subject groups in lieu of taking a Group 6 course. This would result in a student studying an extra language , taking an extra social science or experimental science course, or taking Further Mathematics HL (provided that student is already taking Mathematics HL ). The Group 3 Information in a Global Society (ITGS) course would be taken only as sixth subjects, as they do not satisfy the IB Diploma requirements for their respective subject groups.
Candidates who successfully complete all the requirements of the IB Diploma Programme and one or more of the following combinations are eligible to receive a bilingual diploma: two Group 1 subjects (of different languages), a Group 3 or 4 subject taken in a language other than the candidate's Group 1 language, or an Extended Essay in a Group 3 or Group 4 subject written in a language other than the candidate's Group 1 language.  IB certificates are issued to indicate completion of diploma courses and exams for non-diploma candidate students.
