JLearn (JQuery learn) is a simple program that allows you to learn anything (if a quizz has been written of course!).
From japanese alphabet to maths, passing by world capitals, anything can be learnt.
JLearn interface is pretty simple: one box showing you the question, and one box to enter the answer.
If you don't know the answer, just press the [space key] and it will be shown.
Quizzes are submitted by the community, you can find some here or even write your own!
