If this helps at all, it's closed file. They will have no idea what you said in your application (for me at least it seemed that way). Also, our group was asked things such as: name a difficult time and how you overcame it, describe your most difficult class and how you managed it, your proudest achievement to date, and what you see yourself doing in 10 years. After that, they asked if anyone had anything to add to any of the questions, then it went into discussion. We talked about (basically) healthcare and if it was a right or a privilege. I was accepted! But I made sure to state my opinion but I didn't talk so much that I was overbearing. The happy median is ideal I think. My answer to the "hardest class question" was less than 5 minutes long, easily!
