<p>If you really want to be around STEM people all the time, then Princeton might be too liberal artsy for you. Not to say there is no STEM oriented people there (they’re everywhere), but I am sure there are probably many more at a place like MIT. However, if Princeton is your dream school and you are comfortable with the idea of being around STEM and non-STEM people then you should use your EA there. And I promise, there are going to be plenty of nerds in the at either of these schools, even in the art and humanity departments (despite MIT being all mathy and sciency). And if you want a more meaningful education, you might want to go to Princeton because there is not as many STEM people there. In the end it is up to you. I wish you luck with your decision. Remember have have matches and safeties, though in case neither of these work out for you ('cause you never know).</p>
