Don't stress so much over the group interview! Actually, you should focus more on the one-on-one interview as this is the one where they ask you specifically detailed hard questions about your application (strengths, weaknesses, etc). The group interview is closed-file, so make sure when they ask you to introduce yourself to throw in some interesting topics which you want to talk about later because this is all they have to go on... otherwise you will ened up with the questions that others on this website have said they thought were a waste of time --> ie ''what is on your IPod''. They won't ask you that unless they are fishing for answers and you didnt' give them an interesting topic to run with.
