Definitely know about the school: read their website thoroughly,
What impressed you positively?
the students, the helpfulness of the admissions office -- they walk you back and forth from your interviews, which is great so you don't get lost.
What impressed you negatively?
maybe the cost of tuition and the lack of a gym
What did you wish you had known ahead of time?
nothing really - i felt pretty prepared but nervous nonetheless
What are your general comments?
Their curriculum is undergoing major reform, and this will continue to occur in the upcoming years. Both my interviewers were really nice - the interview was definitely more of an interview rather than a conversation (more focused). Almost everyone I interviewed with had a great day and really enjoyed the school.
