Interval training (Paul Pimsleur)
According to linguistics, an interval training (Spaced repetition) is the best way to memorize a list.
This method is based on repetition. If the answer is correct, it will be repeated later than when it was wrong.
If the answer is correct four times in a row, you have memorized the question and during this quiz the question won't come back.
