History: topic tests

Easy supports recall and familiar applications; Normal requires independent application; Difficult asks for transfer, comparison or justified evaluation. Each level has a different question set. Answers, worked reasoning and question-specific review criteria open after submission.

Long topics sample lessons across the topic. A topic test does not certify complete syllabus coverage. Questions with detected missing source material or incomplete answer guidance are held back. Topics without a complete three-level sequence remain visible as gaps.

The design uses official papers and marking guidance where available. Newly completed topics include subject-specific references; new syllabuses without past papers are labelled accordingly. Retrieval, explanation and spaced review are informed by learning research. This is not a paper-by-paper audit of every qualification, and the difficulty levels have not been calibrated with student results.
