In 2001, MIT (Massachusetts Institute of Technology) implemented a revolutionary program, the The OpenCourseWare Initiative; they put their courseware online, available free to anyone who wants to study it.
Browsing through the 500 courses, I found just what I was looking for: Beginning Japanese I, Beginning Japanese II, and Intermediate Japanese I.
Each course provides the study materials and practice tests with answers. This is the part I really like. I find it difficult to learn from many of the books I have since I don't have to actually do anything. A test challenges me, but it's only worth the challenge if I the answers are available to check my work. This is a great resource the next time you resolve you're going to start studying Japanese again (for the 10th time).

Bush tells us the economy is on the rebound, but MIT is cutting back staff and services.

http://opencontent.org/ocwfinder/ and do a search on "japanese". it'll spit out a lot of results and then use the browser search function to find the 3 entries. PS - There's a great Firefox utility called "Moji" which provides a translation as you roll over kanji. Check it out.
