I think It'd be interesting to see how your friend's achievements are compared with yours and whether being around those people throughout your high school years had any impact on how well you did.
ill be attending UW-Madison
here are schools some of my closer friends will be attending:
UW-Madison (5 friends), Harvey Mudd, Northwestern, Purdue, Minnesota-TC, Rochester, Lehigh
As you can see me and my friends are attending very similar schools academically. I definitely feel that being around those people the past four years had an impact on my achievements in school because seeing them work hard set a good example for me and motivated me to do well.
