How the deck works
1
Cards start in your active deck
A short diagnostic shows what you already know. Cards you miss go into your personal practice deck.
2
Answer and rate yourself
Multiple choice and true/false. Correct? Rate how well you knew it. Wrong? The card comes back sooner.
3
Cards go Gold when mastered
Answer correctly three times with growing intervals. Gold cards review less often so you keep them without dwelling.
