Quizlet

First - it is a study tool. So for the few that believe they can learn a new subject or get in depth knowledge of one from Quizlet, well, good luck. I know that a few actual classes are at the site from various teachers. Never touched one. Second - the best study decks are going to be the one you build yourself. Reason for this is that as you add question and answer this information stays in your memory longer and helps reinforce what you already know. The other reason is that anyone can build a study deck, post it, and you would not know until too late how much that person got wrong or did not verify as correct. One deck I had used had two questions that were wrong, but that subject material was not familiar to me and thus it reinforced two wrong answers. That is of just the ones I was aware of. Third - It is fairly easy and quick to build a deck, but the over all interface is not good. If you compare against Anki, Quizlet is a quick use and easy to build, but Anki is a powerhouse with extreme customization, but has a steep learning curve to do this. Four - The quizzes/exams are horrible. If you build a deck for an entire class or certification, it will randomize the answer choices, making it all but certain you can figure out the correct answer. Not very good for gauging your readiness for an final exam or certification. I have not paid for the 'professional' decks, I would not so maybe those do not suffer that All Choices Except One Are Impossible when 'practice testing'. In short for a study tool it is decent to good if you have the time to make your own cards and to proof read and verify another's person's set. If you are severely lacking this time pay for study materials that are professional and skip Quizlet.
