Flashcards are a great tool for memorizing just about anything and they are simple to create. Just write a term on one side of an index card and the term's definition on the other side. Once you have a stack of them, you can quiz yourself to see which ones you know, putting the ones you knew in one pile and the ones you didn't in another pile. Even if you didn't know any of the terms before you started making the cards, you'll find that through the process of creating the cards you actually learned several of them.
Quizify builds quizzes from information already on the web. It can make a quiz from a web page that includes a HTML definition list or acronyms and abbreviations. Otherwise, you can enter the information manually.
Quizify is designed to really help you learn the subject you're practicing. Quizzes are never-ending, you can practice as long as you want, and some quick stats let you know how well you're doing. Questions are not asked randomly, but based on how much you need to practice that question.
