I know that you still can, but the thing is, I have already gone to the first tut and been placed in a group for group work. We are being put into assignment groups tomorrow, so basically I need to change now, or not at all. See, a spot has opened up at a much more convienent time for me, but I don't want to let my "group" down by leaving, or have my teacher annoyed at me... but the time is much better... What to do?
