1) What language course did you take? Japanese. 8)
2.i) How was the class taught? Similar to high-school language courses? Not similar to high school at all. For one thing, you have to learn your hiragana and katakana within one or two weeks. Another thing, in high school they focus a lot on the order of strokes for writing but in college, they focus a lot on 'good' handwriting. It has to be neat. I'm not sure about the other languages but at my school, Japanese is 6 credits (which is A LOT) and there's class every weekday for Japanese (though second-year JPN isn't like that). A lot of it is focused on speaking and grammar and things of the sort. Vocab is something that you should just instantly memorize when they flash you the words (study it in the books). And yeah, there's a lot of role-playing in first-year Japanese...I'm not sure about second. xP
2.ii) What makes a good (or bad) language professor? A good language professor can SPEAK ENGLISH.

Our professor had an accent but he was still comprehendable. He was witty and funny and good professors will generally be like that. Though...he should make an effort to try and remember your name...he never remembered me...despite how ever many times I told him...xDDDD But I'll be honest, I learned more from the teaching graduates from our recitation classes than from our professor during lecture.
3) Any tips or stories that you could provide? Well, my JPN class went about teaching the language through the book and they provided a syllabus on everything we were going to do for the day.

So basically, I just went through our activities from the books, wrote the answers down, etc so that I wouldn't look like a dumb idiot when our instructors called on us. Oh, and don't be afraid of anything when you have to talk in front of the class, etc. You'll be with them for a while so get used to it.

They're generally very nice and you'll probably make some cool friends. 8)
4) Any good study habits? o___o;;; Just study everyday...xD Buuttt, let's see, we had some study groups before. At class, we had oral interviews to do and so studying with groups is really helpful (and even more helpful if one of your buddies has gone to the interview already and knows everything that went on).
5) Anything else you feel like sharing 
Personally, I think JPN class is fun. xD Why? I suppose it's because by the time you're used to your classmates, you'll all be like family.

Don't be stingy and make some friends, no matter who they are.

[Specific to me: Has anyone taken dual language courses (two different languages at the same time)? Do you think it is a good idea to given your experience?]
It depends on your motivation. If you reeeaaallly rreeaaalllyyy rreeaaalllyyyyyyyyyyyyy want to take it, then
DEFINITELY DO IT because later, you'll probably want to really do it but realize you don't have the time for it. ToT;;; And even if your adviser 'advises' you not to do it,
DO IT. I seriously regret not taking two languages my first year. My adviser told me it was better just to learn one language and then learn the next language next year. Gawwdd, she wasn't right at all. >.>;;; Now I don't have time to learn it (my current adviser won't let me take it either because i need to 'finish all of my needed credits' when I can't even find anymore classes that fit my schedule that are 'needed credits'...might as well take it, right?!)...jeez. Anyway, I met a girl who was taking Japanese and Korean. And y'know what? She's the smartest girl in our JPN class and she's so dedicated and she did really well in her other classes too. I mean, maybe she's just smart in general but she was pretty determined and managed to do it successfully!
