I took it for two semesters in college, but always found the professors--even the Japanese one--far too lenient. They emphasized sentence structure without teaching us vocabulary. Don't get me wrong, structure is really important, especially in Japanese, but you won't learn a language without a hardcore regimen of vocab. I try to learn on my own, but it becomes too much of a chore. The only thing I really find intimidating is learning Kanji, even though it shouldn't be...How about yourselves?
