Also: Remember that not all CS classes will have CS in the title. At Thacher, CS is central to the Astronomy work since they have to write the code to run the THacher observatory and analyze the data. (Last year, they were the only HS to send a team of researchers to present alongside universities at a major conference…)
(Didn’t mean to promote Thacher. I know you are dead set on Exeter, which is hard enough to get into… and THacher’s acceptance rate is even smaller. Just 9 percent for those requiring financial aid, 12 percent overall!)
