More importantly, those taken in the later waves might already have had to submit tuition payments or even move into/begin classes at their current school. Since freshmen won’t even be taking classes (well, just one) at Brown this fall, it’s less of an issue for them; but it would be pretty heart-wrenching (for me, at least) to get offered a spot at Brown and not be able to take it due to already being locked into another school.
