A 33 ACT & 3.7 UW puts you slightly above the median for BU (32 ACT & 3.8 GPA), making it a match for you. AU had a spoof year where it had a more selective acceptance rate, but for AU 2021 it was ~30% overall with a 28 ACT/1260 SAT and 3.6 GPA. GW is comparatively easier to get into with an acceptance rate of ~42% for 2022.
BU is a match, and GW & AU are safeties.
