I definitely urge you to keep your interview at Drexel. I ranked drexel lower on my list before my interview, mostly based on location. My interview changed all that. I was impressed with their curriculum and the vast opportunities for clinical rotations. Particularly was their approach to education. Drexel has 2 tracks you can choose from for your first 2 years of education. IFM is the traditional one: go to lecture 6 hrs a day or just study the class notes, hope to kick *** on the exam, chalk up 2 years of your life to the cause. PIL is a problem based curriculum where you meet with 6-8 students and an instructor 3 days a week for 3 hrs, approach science from a unique perspective that incorporates clinical relevance, go to lecture/lab for a few hrs and actually have a life in medical school. I choose Drexel and PIL and was extremely satisfied with the way I spent 2 years of my life. BTW, our passing rate for the boards was just as good as IFM.
Good luck.
