4,087 numbered questions or named language tasks across 250 source PDFs in this subject/level selection. Repeated copies of the same extracted question are grouped once. 116 entries still need topic classification. Optional essay and text choices are included; these counts are not the number you must answer in an exam.
Question anchors and printed allocations are extracted from SHA-256-verified source PDFs. Optional alternatives are not added together. Applicable all-question paper totals are reconciled with the printed rubric; mismatches withhold automatic mark totals. A first written-answer marking row is never treated as a whole-question total. Exact marking pages require a section-matched table anchor or a wording- and digest-checked source pair. Topic headings are conservative rule matches and provisional, not independently reviewed or proof of current syllabus coverage. Original questions, diagrams, passages and official answers are not republished in this metadata index. Checked original question pages are rendered on demand in the website without rewriting their wording or diagrams. Scans, extraction gaps and uncertain marks remain visible rather than filled with invented content. Source audit: 2026-10-21. Question index: 2026-10-23. There were no ordinary exam sittings in 2020 or 2021. This is not a claim that every question has been independently checked or that scanned papers are fully indexed.
