More skills.
Less repetition.
524 distinct skill groups across 14 subjects. Find a question type, open an example in its original paper and check the published marking instructions. Repeated appearances are grouped, not duplicated.
Practise from the original PDFs, then return to record completion and optional self-marks. These are 524 rule-assisted skill groups, not teacher-approved worked answers. Each example links to its matched numbered questions in the same practice index. Automatic topic and marking matches remain distinct from wording-checked pairs. Older formats and scan gaps are listed below.

What is covered, and what still needs review?
Skill groups are derived from the same numbered-question index used in practice, with exact question IDs retained on every example page. One entry per subject, level and family; repeated appearances are grouped rather than additional types. Source pairs checked against wording and PDF digests are distinguished from automatic table and rule matches. Classification is provisional, not a claim of exhaustive syllabus coverage or independent subject-review sign-off. A historical appearance does not establish that the skill remains in the current syllabus. 3 scanned question papers need OCR. 2020 and 2021 exams were cancelled. Older questions can use different course or marking formats. Counts below are skill groups and linked question documents, not question counts or exam predictions. Counts awaiting classification now refer to numbered entries in the shared question index, not arbitrary text fragments.
