I had classes on Wednesday, Thursday and Friday, studying at the library on Saturday and I volunteered (through my Uni) on a Tuesday! The three weekdays of classes were typically from about 9 or 10 to 2 or 3 in the afternoon (except for the one class going until 4pm in term 1). I was pretty much busy everyday except Sunday and Monday! This year (my 3rd) is pretty much the same except on Wednesday I only have one class at 10-11am. Friday I'm on from 9-5 though, so that is going to be my worst day!
