RecallPlus will test you on all cards you have seen, in an order determined by:
How well you have recalled the cards in the past
How significantly you have weighted the individual cards
You can alter this multiplier/divider number.
To do this, select Options / Preferences / Timing and type in the new multiplier number. Then click "Apply" and "OK".Note that the default multiplier and timing are set in response to research on effective learning techniques.
It would be beneficial to your learning to leave these defaults in place!
