Do you know kids at Lehigh (or recent grads)? Just curious. It is as much a “fit school” as some of the others mentioned, but unlike an urban school where a kid at MIT can have friends at BU, Wellesley, Tufts, Harvard (which MIT kids call “Cambridge Community College” even though there are a lot of Harvard/MIT ties!), Northeastern, Brandeis, etc- Lehigh is a skootch more isolated (without a car, socializing with kids at the other colleges in the valley is challenging). And smaller. So seems a bit riskier choice for a kid in California who hasn’t visited.
OP- good luck. Your kid sounds fantastic!
