Today was registration, which was pretty straightforward. In a surprising twist, registration was actually simpler here than at SJC--the one and probably only time MIT will be less complex as an institution. I over-loaded up front to "shop" classes, as the upperclassmen recommended, but I'm sure I'll be down to a normal schedule very soon.
Later in the day I went to a Civil Engineering BBQ. I'm not sure I was supposed to be there, but it was great, because I got to meet people whose work has some overlap with what I'm interested in. I met some professors (some of whom teach in DUSP), and it was overall a great event.
