You’re a reach (but not an unreasonable one) for WashU, Vandy and Georgetown. You’re a low match (25-50%) for Emory. For schools a bit higher up the selectivity ladder than the first three (at least 7 of the Ivies, S, M, NU, Duke, UChicago, maybe 1-2 others) you’re likely spinning your wheels, so I think you’ve set your reaches well.
Your UWGPA really isn’t that low and your course work appears to be reasonably rigorous based upon the APs listed and bumping that up to a 4.5 WGPA. What is the weighting method here? 1 pt boost for AP and 0.5 for honors? As far as your Bs, what specifically are they in? As someone interested in political science/international affairs, I’d place your subjects in the following tiers:
Social sciences/history/English
Math
Natural Sciences
FL
Other core (health, gym, music, art).
Your ACT is your biggest weakness. Not a dealbreaker, but a 33-34 would be helpful here.
Thinking strategically: if you view all four of the schools listed on fairly even terms and would be happy to attend any of them, your best bet is applying to Emory Oxford ED1/WashU ED2. Or maybe WashU ED1 and Emory ED2. I mention these two schools because Georgetown lacks ED, Emory is by far your best shot and WashU is a bit less rigid wrt to the quantitative aspects of the app compared to Vandy. If you’re really not sure and are considering other schools (and the recs in this thread are good ones), there is nothing wrong with staying RD.
Fwiw-former pre law track (polisci and econ) graduate of WashU with a good current understanding of the school. Happy to talk about my experience there, but you could have a good experience at any of these schools or others that have been suggested.
