Quizlet

"Quizlet is very helpful for all types of students. Quizlet can help the student learn the definition with the flashcards, learn to spell the word, and even play games with the words that are in the particular study set. Quizlet can also create a practice test that consists of multiple choice, true false, fill in the blank and matching. There are quizlets that are already created for many subjects, but users can also create their own." https://en.wikipedia.org/wiki/Quizlet

"Quizlet makes simple learning tools that let you study anything. Start learning today with flashcards, games and learning tools — all for free." https://quizlet.com/
