We had the oppurtunity to talk with M1-M4 students throughout the day...they told us what medical school was "really" like.
What impressed you negatively?
If I hadn't known the campus I might have really been nervous about findings out where my interviews were located. They do point you in the right direction but it's up to you to find the door and the room.
What did you wish you had known ahead of time?
Although I took the "fashion over function" approach, wear comfortable shoes if possible...you will do alot of walking.
