Empirical exam prep skill. Fuses past-paper frequency analysis with lecturer's
emphasis on a small course-specific corpus (3-7 past papers + lecturer review)
to produce ranked study plans + drill-ready PDFs.
Unique capability: surfaces discrepancies between what the lecturer emphasizes
and what they actually test (the "TRAP WATCH" quadrant).
V1 SCOPE (full support): closed-book written exams with deterministic answers
(calc-heavy STEM, IB Math/Physics/Chem HL+SL, NTU/NUS engineering, finance).
V1 PARTIAL: proof-heavy math (skips verbatim drills), MCQ board exams (Anki-only).
V1 NOT SUPPORTED: live coding (redirect to /investigate), essay-heavy humanities
(V2 sister skill /essay-prep planned).
Triggers: '/exam-prep', '/cram', '/drill', '/临时抱佛脚', 'exam prep',
'past paper analysis', 'study for exam', '考试复习', '过去试卷分析',
'临时抱佛脚'.
