Here's how it works: You enter a vocabulary list of any words or data you want. (ex. SAT words, history dates, French-Spanish translations, etc.)
Quizlet gives you a specialized learning mode, flashcards, randomly-generated tests, and collaboration tools for classmates to help you study those words. You ace your test. - Quizlet keeps track of the words you know and only retests you on the ones you don't. - You can share your word sets with classmates and get email notification when others make sets for you.
You can import words from a file without having to retype them into Quizlet.
Quizlet has accent buttons for typing letters in foreign languages. You can discuss sets (and gossip about teachers!) with classmates via instant discussion boxes. Quizlet works in any language. If you can type it into your keyboard, you can study it on Quizlet.
