Builds a day-by-day exam revision timetable from your exam dates, subject weights and confidence. Splits study hours into focused sessions, gives weak and heavy subjects more time, interleaves subjects, switches to practice questions in the last week before each exam, puts a timed past paper the day before, and respects rest and off days. Flags too few sessions per topic and back-to-back exams. Includes a stdlib Python planner with --self-test.
