I created a public Memrise course on OCEJWCD
JEE 6. Memrise is a free "flashcard" type website that quizzes you as you go along. It's free. If anyone else wants to contribute let me know. I created it for me and figured it might be useful to others here. I haven't taken the exam yet, so not certain how useful it is.

Not selling or promoting anything and I have no affiliation with Memrise. If you see any errors let me know so I can fix it.
