I have figured out what to do. Since I'm taking a short summer course(one week right after finals in May and one week before school starts in August) which is worth 2 units, and I have signed up for a one week's course about Linux(worth 1 unit) I have 15 units this semester, therefore I don't have to take another class instead of the one I couldn't take. So I only have 3 classes this semester! Which means I will only take 3 finals (instead of 4) ;-) Makes a little difference. I don't have classes on Fridays but that doesn't mean that I have the day off, I will use it to catch up on my homework. Last semester I had Fridays off too most of the time, just one class once in a while that day.
I really recommend this movie, Facing the giants. I have already seen it twice and it's one of the best, if not the best movie I have ever seen! I really like it. It's a very good movie, with a great message.
