Early in the interview season, I was rapidly falling in love with New York City. . . even if the housing situation called for a dorm or 4 other roommates. WingZero- asking the same question as adebola- did you want to go to Michigan or would you have wanted to stay in NY? When you said you're from NY, did you mean City or State?
Michigan was my first choice. adebola- A choice between Michigan and Duke?? I can't help you with any info on Duke. . . I know someone who went there for undergrad and she said that Duke, as a school, is pretty cool, but that Raleigh isn't that interesting as a town and that she would always go to Chapel Hill for kicks. Again, I can't share personal experience.
BUT, I'm biased towards Michigan. I had a good set of interviews at good places and Michigan was the best experience by FAR. In the end, I had 5 acceptances and 4 waitlists, I got into Michigan straight. I passed on instate tuition at UCSD to go to Michigan. . . I liked Ann Arbor, it's a cool, progressive college town, it's a beautiful area, lots of opportunities for volunteering and/or research. . . and the students all seemed really down-to-earth and diverse. I'm really excited about the decision, but who knows if you'd like it. Duke is a great place too, it's all a matter of what you'd like, what kind of environment, etc. What were your first impressions of both places? What's important to you? I know this sounds hokey, but go with your gut reaction to each place.
