I can address a couple of these things!

1) Email the Faculty. Explain your situation as clearly as possible, and see if they will enroll you. That way, you'll at least know if you can get in or not, and can find something else, if need be. The Faculty is usually pretty quick at responding. :)

3) I addressed this below, but they are typically due the next day (at least they were a few years ago when I took physics).

4) I had a night class once. I disliked it, because I was just flat exhausted the next morning. It screwed up my sleep schedule because I didn't get home until late, and then typically still had homework to do. If you live on campus, you'll be a little better off that way (my commute was a half hour at that point). Also, they cover a lot of material in 3 hours, and we didn't get any breaks, so by about halfway through, pretty much everyone had stopped listening. These two things in particular made me swear to myself I'd never take a night class again (and I've never looked back!). If you can find a way around taking the night class, do so. If not, just suffer through the night class.

5) Your schedule looks pretty decent! I would be happy(personally) with that schedule. The only thing I might mention is that if I could go back and take physics again, I would have done Friday afternoon labs (bear with me!). The lab reports are quite time consuming, and are due the next day. That means that if you have a Monday lab.. It's due Tuesday. If you have a Friday lab? Due Monday. :) << that's the only thing I want to mention pertaining to your schedule. :)

Best of luck next year!!!! :)
