go ahead and grasp yourself some good winter courses as soon as possible! once the time slot opens, people can register any courses for both fall and winter terms (of course you can wait until January for winter courses-----if there is anything left by then). many of my beloved courses in winter have been closed, and my time slot hasn't been open yet!
actually I was trying to registre for some winter courses earlier. However, I kept getting "reserve closed" for most of the courses. I was very worried that I couldn't get into those courses. Any suggestions?
