No, what you see is what you get as far as lectures go. Aside from duplicate lectures, where you just pick one, you'll go to what's on the timetable. The only thing is tutorials. Options for times for them may or may not come up, what you'll have to do is sign up for them around the first week of class. Tutorial times are given on a first time first serve basis, so figure out roughly when you want them and get them quick.
