IB Diploma candidates must choose 6 courses in total, 3 of which must be at the higher level (HL) and 3 at the standard level (SL). Students must also take a language appropriate to their level (see our language policy), and this may mean that they choose a language in their mother tongue. If a student does not want to select the art option, a group 3 or group 4 subject must be selected in its place.
