ummm.. I liked the school. I got a really good vibe. Everything's pretty new, the classrooms and all the technology are up to date (plug for each individual chair for your laptop, they have microphones hanging from the ceiling in each row so if you get called on and are in the back row, they can still hear you haha)... I'd say though that a lot of the people who were visiting and those that were current students were young, either right out of undergrad or a few years .. so if you're a nontrad looking for more people of middle age I'd say you may be a minority (or I just went to ASD that had few older students). If you have any specific questions feel free to ask. Since its the next day, what did you end up doing??
Seton Hall.. I know nothing about Mercer
