There are two speaking tests and one listening test (for Japanese 1A). In the first speaking test, it's just a basic introduction of yourself (Hello, my name is.. I'm doing such and such, etc) and the reading of some sentences in hiragana. The second is a themed speech where you have to cover specific points (the use of adverbs, past form of verbs, etc) and answer some basic questions your teacher gives you. The listening test was soo hard (they speak soo quick!) and covers all the stuff you've learnt up to that point (just past half the semester). The quizzes you don't have to worry about. There were four in total, but you only have to do two. I only did 3 of them, and that was because I stuffed up my first one. They're online and multiple choice, so everybody full marks them.
They weren't really ready for the amount of people enrolling into Japanese, so at the start they were quite crowded (25+) compared to my other subjects (~15). Not sure of the exact number in the end, ~20 maybe? Since we're all beginners, the teacher will help you along most of the time. If you're lucky, you'll have nice classmates who'll whisper answers to you, too.

They start from scratch, so it's manageable. I'm still crummy at writing, though, which isn't a problem at all for the Chinese adept doing the same subject.
I'm not sure I'll be doing Japanese for that long, but since you get 8 breadth subjects, you can use them as credit towards a diploma. If you do 8 Japanese subjects you end up with a diploma. If you do less than that, I don't think it gets a fancy name (at least in my course. Might be different in a BA, though).
