I was an Early Decision applicant to Hopkins, and there were a few clear-cut reasons why.
First up, Location. As an incoming International Studies major (who then switched to Political science/french cultural studies), being close to DC was important for me. The more I learned about Hopkins, the more I found out that Hopkins could deliver - a train ride to DC is only 40 minutes and 7 dollars! Moreover, there is a program called the Aitcheson fellowship in which students spend a semester of full politics immersion in DC - live there, study there, intern there. That's pretty great and I plan on doing it.
Next up was the campus vibe. It sounds tacky, but when I stepped on campus, I knew that there was something special about this school. When I got here, I toured around campus, ate lunch at the dining hall, picked up a copy of the black and blue jay (our humor newspaper) went to the bookstore, and even felt comfortable enough to put up a small poster on a bulletin board! (I knew that wouldn't be the last time I saw that campus, and I wanted to leave a mark.) The people I met seemed motivated, nice, and funny (one girl sensed we were lost outside of the bookstore and we ended up chatting for about 10 minutes about all things hopkins) and the campus itself was just beautiful and inviting. I knew that I could spend 4 happy years here.
Finally of course, I was drawn by the strong academics here at Hopkins. Here we have incredible professors, a top-ranked IS program, the oldest french program in the country (with some wonderful programs to prove it, like a "teaching french in public school" course/internship!) and students all surrounding you who are equally as motivated and high-achieving. But more than that, even the way academics are structured is wonderful. We have no core classes, like english 101s that a lot of my friends at other colleges were forced through. We instead have distribution requirements, which is a very liberating system. Also having covered grades the first semester, meaning that your first semester grades don't show up on your transcript and don't factor into your GPA is really nice - and for those of you who want to work hard and be recognized for that work, don't worry! If you make Dean's list then even though your grades won't show up, it will say you made deans list, which tells grad schools and the like a lot.
