I talked to friends that went to the school, read the literature sent out by the school, and memorized a list of questions. Remember to re-read your essay as I was pretty much quizzed on it.
The new clinic building, and spending the day with one of my friends experiencing the day of a dental student (3rd year)
What impressed you negatively?
The janky tour given by the admissions secretary (she didn't know what most of the rooms were, luckily my friend gave an additional tour)
What did you wish you had known ahead of time?
Most of the buildings were somewhat run down, and it's in the middle of the ghetto (I knew this before, but it took driving to the school for it to sink in.) Oh, and they have odd policies on renting instruments and sending out labwork.
