Source material. Everything in the Paper 1 notes is built from what is here.

The Legend archive

Every past question and mark scheme, sorted by syllabus bullet rather than by paper. If you want to know how a particular bullet has been examined over five years, this is where to look. Each entry gives the question ID, the question image and the mark scheme image.

The PDFs live under 03_Resources/docs/; the markdown indexes are listed below.

How to treat 9608 material

Always prioritise 9618. The 9608 archive is a supplement, not an equal source: parts of it cover content the current syllabus has dropped, and at least one section is mis-filed by its original author. Use it to fill gaps in 9618 coverage, never to override it.
