No problem! I remember that the interview was very relaxed and informal imo. I was asked a lot about how I prepared for the mcat, and also about my academic shortcomings. Be prepared to speak openly and honestly, but also try to make your answers positively highlight your strengths. I was not asked about my achievements/experience, and I remember the questions were a mix of standard and "fun" questions. The interview isn't anything to stress over but again be prepared to prove that you are ready to work and can handle the work.
For housing, I am considering renting an apartment near the center city campus or in east falls (near the med school). I say this because I applied to another graduate program at drexel and past/current students have informed us that most ppl live near the med school because that is where they spend majority of their time (not sure if this just applies to students in that program). I received an email from the IHS administrator who provided me with the contact info of the IHS mentors so I can definitely ask them for housing advise!
