The International Baccalaureate runs across the high-school years in two programmes: the Middle Years Programme (MYP, ages 11–16) and the Diploma Programme (DP, ages 16–18). Each year below is a course you can focus on; topics not yet written appear as greyed placeholders so you can see the whole syllabus.
(The DP maths courses — Analysis & Approaches and Applications & Interpretation, each at SL and HL — are split here simply by year; the year pages note which strand each topic belongs to.)
