Review cards and your daily review
Key terms from your lessons come back just before you'd forget them. A few minutes a day is enough.
Spaced review brings each card back at the right moment: soon if you found it hard, later if it was easy. That way what you learn stays with you.
Where cards come from
- Your lessons. When you finish a lesson that has review cards, its cards join your review.
- Your notes. Press Make a review card on a note or highlight to turn it into a card.
- Questions you missed. When you miss a challenge question, the key idea behind it comes back as a card.
Do your review
- Open My account and choose Spaced review. Your account's Today card also shows how many cards are due.
- Press Start review.
- Read the card, think of the answer, then press Show answer.
- Answer How well did you remember?: Again, Hard, Good or Easy.
In a lesson's Review cards tab (in the Study panel) you can also practise by matching: under How to practise, choose Match, then pick a term and the definition that goes with it.
Finishing your review (every card due) counts for your week: your weekly goal and your streak (see Weekly goal and streak).
