Harvard vs. Princeton vs. MIT vs. University of Pennsylvania (Vagelos)!!!

<p>Hey Guys!</p>

<p>I was recently accepted to Harvard, Princeton, MIT, and the Life Sciences Dual Degree program at University of Pennsylvania and I am having a difficult time choosing between the four. </p>

<p>I have not visited so I need some third party opinions. If anyone could give me any helpful information relating to these schools, it would me much appreciated : )</p>

<p>I'm looking into majoring in economics and a type of biology. </p>

<p>Thanks!</p>
