I think the 100 acceptances number (and subsequent post II acceptance rate) is way too low. US News says that last year they needed to accept 299 to enroll 101. That means that they needed to accept 3x their enrolled students. This makes sense because even though it's free tuition the geniuses getting in here are also probably getting full scholarship offers to other T10 schools that may be closer to home, better climate...etc. So although they may claim that their yield is close to 100 percent, it just isn't true. I know that initially they may place a lot of people on hold, but eventually they DO end up accepting close to 300 (assuming US news is correct and it has been pretty close to accurate for almost every other school). Don't give up hope, people.
