The statement "To make the most out of a flashcard, you should put as much information as you can onto one card," is FALSE.
A flashcard or flash card is a card bearing information, as words or numbers, on either or both sides, used in classroom drills or in private study. A question is written on a side and an answer overleaf. Flashcards can bear vocabulary, historical dates, formulae or any subject matter that can be learned via a question-and-answer format. Flashcards are widely used as a learning drill to aid memorization.
