well team GMS is a sort of lecture cum tutorial that is peculiar to Duke-NUS basically u are given a problem and asked to think about it at home then when u get to school u are asked to answer questions based on the problem first alone then as a team. For the team GMS sessions that are scheduled during the interview days they try to replicate the kind of learning style that students at the school actually do every week. it is quite similar to the problem based learning that most australian graduate schools have the only difference is that in normal schools you have two years to study basic clinical science but at Duke-NUS you get only one year before you are thrown in to the public hospitals so it really takes a lot of self study. I can't really talk to much about my experiences as the school wants every applicant to experience it on their own but overall I can say that it was totally new and refreshing. Good luck with your interviews be it at san fran or duke.
