Regarding Kenyon, 17% of their incoming students originated from the top 1% of their high school classes, so, essentially by definition, many of them arrive with remarkably strong quantitative skills. In terms of sciences specifically, the school has supported a recent Apker Award finalist (physics) and tends to have notable success with medical school placement.
That said @Josh700, your list of colleges seems excellent and appears to be one of the most well considered and cohesive that I’ve seen on CC. I’d personally suggest no more than one or two additions or removals.
