Portfolio Review Suggestions

We are looking to host a student portfolio review (and 2 months following, a professional portfolio review) in the Minneapolis area for IDSAmn chapter. Aside from the typical format of 10-20 minutes with a reviewer, I was thinking that the best benefit for students would be to having things broken up into groups that would cover quick basics, like interviewing tips and how to break the ice/network. Any thoughts or suggestions? Any positive/negative impressions when taking part in a portfolio review to keep in mind?
