Keep the lesson behind each wrong answer
Save the question, your original answer, the correct method and a note about why the mistake happened. A short next-time reminder gives each card context when you return to it.
Review with active recall and spaced repetition
Hide the answer until you are ready, then rate your recall to help schedule future reviews. Use scheduled cards for ongoing revision or separate practice for extra exam preparation.
Organize revision around your subjects
Group material by subject, chapter, exam or tag. Review due cards, recurring mistakes and weak topics, or begin a focused five-minute session when time is short.
Keep your study library recoverable
Create a local backup or choose optional Google Drive backup and restore. Backups include study media, answer masks, review history and schedules; they do not provide live editing across devices.
