Spaced Repetition

Options Flashcards

110 cards across 5 sets. Flip, rate your confidence, and build retention with spaced repetition.

How It Works

1. Flip & Read

Tap the card to reveal the answer. On mobile, swipe right (easy) or left (hard).

2. Rate Yourself

Mark each card Easy, Medium, or Hard. Hard cards reappear more frequently for spaced repetition.

3. Review & Repeat

At the end, see which cards you struggled with. Filter to practice only the hard ones.
