Each question has four multiple-choice options and detailed explanations directly relevant to exam preparation. You can steadily improve your scoring ability while understanding "why" things are the way they are. ◆ SM-2 Space Repetition (Spaced Repetition Learning) The scientifically proven SM-2 algorithm automatically schedules reviews. • Correctly answered questions are reviewed at gradually increasing intervals for efficient long-term memory retention. • Incorrectly answered questions are re-presented at shorter intervals to focus on reinforcing weaknesses. • The app manages "when and what to review," so simply open it and answer daily. ◆ Learning Tools to Aid Memory [Notes] Write down your memorization techniques for each question to create your own personalized reference book. [Bookmarks] One-tap to register difficult problems and review them intensively from your bookmarks. [Random Questions] Questions are shuffled across different areas. Prevents rote memorization and helps develop your test-taking skills. ◆ Motivation-Boosting Progress Management [Learning Streak] Records consecutive learning days to encourage habit formation. [Learning Record] Visualizes the number of answers and completed problems. [Achievement Animation] Celebrates with confetti when all questions are answered correctly. ◆ Smart Notifications to Never Forget Review Set reminders at your preferred time. Notifications display "Number of Questions to Review Today." ◆ Try it for Free First Start immediately without registration or payment.
