Classes 1 to 3 open the kid player: one question at a time, a second chance before the answer shows, stars at the end. Classes 4 to 10 open the exam player: OMR answer sheet, explanations after every answer, a scorecard, and fresh questions on every re-roll.
Save stars, mistakes, review schedules, and practice time to a JSON file, or restore them on another device.
