The QB school list has so many fabulous schools on it that it can be hard to pick.
For your interests, MIT seems like a wasted spot. Tufts or Rice might be better. I had the same question about LACs - so many are strong in your area of interest. Colby, Bates, Amherst, Haverford, Vassar….
If you can match, it’s a great deal with QB, so it pays to use it for schools that are a fit and to be strategic. Perhaps the top 8 of your list can be from your list above and the other 7 can be ones you like – maybe even more than UW – where there is real fit and better odds. There’s nothing to say you can’t apply to other schools in the RD round if this doesn’t work out, but it feels like a missed opportunity to not explore a bit more and find a fit.
You look like a strong applicant. I’d add your SL scores to your profile as support of your grades in those classes if the scores were decent.
