I am not really sure how to help you with this choice.
Maybe, on the margin, Groton has the least athletic student body? Everyone is required to participate in sports BUT that makes the JV and thirds teams very fun. I wouldn’t say varsity athletes are kings of campus at Groton.
Groton has a strong humanities department and good arts programs, but my guess is that Choate and Deerfield do as well. Tagging @Golfgr8 and @CavsFan2003.
