More skills.
Less repetition.
529 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.
Source-linked practice, not a complete new question bank
These are provisional skill groups linked to real papers, not copied questions or newly written worked solutions. Repeated appearances share one entry. Some text still needs classification and 3 scanned question papers need OCR, so not every type is verified yet.
2020 and 2021 exams were cancelled. Older questions may use a different course or marking format.

What is covered, and what still needs review?
Rule-assisted question-family grouping from the audited PDF text. One entry per subject, level and skill family; repeated years and examples are grouped, not separate types. Identical normalised page text within a sitting is linked once, preferring split papers over combined copies. Sources open the original PDF page. Classification is provisional, not a claim of exhaustive syllabus coverage or independent subject-review sign-off. Counts below are skill groups and linked question documents, not question counts or exam predictions. Text-segment counts may include extraction fragments and are not counts of unclassified questions.
