All HL past papers by session
Each link opens that paper’s own page. The codes show which variants or versions it holds.
Past paper content © International Baccalaureate Organization. The official specification and the latest papers are on the IB Diploma Chemistry page. If a file says it isn’t in the collection yet, it simply hasn’t been added.
Prefer Practice by Topic?
Full papers are best for timing and exam technique. For one weak topic at a time, use the Diploma topic-wise resources or the resource search. Other boards and qualifications are on the full list of past papers.

Are Standard Level (SL) papers here?

Why is there a short wait before a paper opens?
