Choose the country and stage you are entering. Exact paper editions appear before broad official collections. If a year or stage is not indexed, a labelled collection may still help; it is not a confirmed match for that choice.
Search covers country names, competition names and stages. Topic search within individual papers is not available. For topic exercises, use the four-subject practice plan.

When no national paper is verified
Some organisers publish only selected material, sell books, or supply papers through schools. We identify those limits rather than offering unofficial scans. For Argentina, Kenya and Morocco, use the new country guide to request an appropriate first-stage set. Public access to a file does not by itself grant permission to copy it onto another website.
