Does anyone have recommendations for good summer programs for high school students? Preferably they should be in an academic environment (e.g. at a college), residential, and have strong financial aid. I know a couple that I did, but they were short and/or non-residential, and they were all specifically for girls in science or math. I'm curious about the broader set of things one ought to be encouraging high school students to apply for right now, and finding it somewhat strange that I don't know.
