Students who opt to study Biology, Chemistry or Physics at Standard Level also attend the Higher Level lessons in these subjects, as much of the common Higher and Standard core material has to be covered before students can study the optional themes.  

Students who opt to study Higher Level Mathematics may be asked to begin the course by studying 4 Higher Level subjects as this course is a challenging one and students may not find that it is suitable for them. For students in this position, their progress will be reviewed after the January exams in Year 12, where they may drop one Higher Level subject down to Standard Level.
