What the result means

The result highlights difficult cards because they require more review attention than already-known cards.

Mastery rate = known cards ÷ total cards × 100. Review time = total cards × seconds per card ÷ 60.

Review quality matters. Mark cards honestly to avoid overestimating mastery.

Example calculation

With 200 cards, 130 known, 45 difficult, and 12 seconds per card, mastery is 65% and one full review takes 40 minutes.

Tips for better results

  • Prioritize difficult cards first.
  • Keep sessions short enough to maintain focus.
  • Retire mastered cards gradually.
  • Use spaced repetition for long-term retention.

FAQ

How many flashcards should I review each day?

Review enough cards to cover difficult items first while keeping each session manageable.

How often should I review difficult flashcards?

Difficult cards should appear more often until recall becomes reliable.

What is a good flashcard mastery rate?

A mastery rate above 85% is strong, but difficult-card load should also be low.

How long should a flashcard review session be?

Many learners do better with shorter focused sessions instead of very long reviews.

How many flashcards can I realistically learn in one week?

That depends on difficulty, review frequency, and available study time. Use weekly review load to plan capacity.
