Rosetta Stone

Rosetta stone is horrible by tself. If you're going to use it for Asian languages, I recommend using it only for practice. Don't use it as your main source of learning. Not only does it like taking shortcuts, but it makes things way too complicated at the start.

I'm taking a Japanese class in school, so I'm not really using it alone, Rosetta Stone doesn't teach you much of anything about sentence structure (i.e. particles). Its fine if youre lazy and a horrible at self-teaching, but, it would be a good idea too have some other materials to learn from.
