WashU is pretty big on interdisciplinary learning and flexibility. I knew a girl who was a Spanish and Women, Gender, Sexuality Studies double major and pre-med. She’s now in med school. I know there were also a lot of classes designed for non-majors to take (like an architecture course for non-architects or business courses for non business majors).
As far as being scared goes, I think the university has really been putting its resources towards addressing what’s been going on. There’s a center for diversity and inclusion that has really been a great resource for students (in addition to the existing Social Justice Center). As someone who is a minority, I wasn’t really afraid there. As someone from IL, I’m not exactly sure the Chicago police would be that much better- I don’t know what the Baltimore police would be like.
WashU does also give free metro passes for all four years and summers.
Congratulations on all of your acceptances! You have great choices!
