What do you want to do with CS? A close friend’s daughter just graduated from WashU’s business school with majors in CS/finance/math. She interned for JP Morgan last summer and got a return offer, so she will be working in NYC starting as a IB analyst this month.
(She had higher grades and SATs than you have listed, but average ECs in high school. She got great grades again in college, but never considered transferring.)
She had a great student experience — WashU is known for fabulous food, dorms, and other amenities — and had great offers.
You may be considering a different direction that WashU can’t offer, but I wanted to share her experience.
