Urbancatfitters–I agree with the others who say that Vanderbilt would not have admitted you if they didn’t feel that you could handle the academics. It is a great school and if Vandy meets all of your financial need and you can graduate without significant debt; grab that opportunity!
Regarding your concern that you might not “fit in” since you are from an inner city, low income family–read this article about the Posse scholars from the Vanderbilt Hustler student newspaper: http://www.vanderbilthustler.com/news/article_a97d502c-b787-11e4-a096-9f11a9888117.html There are groups of lower income students from New York City that come to Vanderbilt every year as part of the scholarship program–and that is just one example of Vanderbilt’s commitment to economic, racial & religious diversity. There are lots of students from public high schools and various economic backgrounds at Vandy, you can easily find people similar to yourself.
All of that said, it may not be easy on campus, you will be surrounded by students who drive BMWs or Porsches and think nothing of spending money on new designer clothes, dinners at expensive restaurants and spring break trips to exotic places.This is from the Duke University student paper the Chronicle about a girl who felt she never fit in there because she was poor: http://www.dukechronicle.com/articles/2013/11/11/i-came-duke-empty-wallet#.VOf5US7qU20 it raises a lot of good points that would apply equally to a Vanderbilt student in a similar situation. Regardless, if you are determined and recognize that you are being given a wonderful opportunity to attend a top tier school where you can get a great education with little to no debt, you should do just fine at Vanderbilt. Best of luck to you!
