Hey,
There is a GEM rep for MedSoc who often posts in these forums who can answer more specific questions. But I just thought Id pop in too. I did not do the GEM entry course, but some of my friends have and I can try to answer any questions that you have. So if there is anything you want to know, feel free to ask.
And if not, good luck with all your applications!
