Wow, this is so disappointing to hear! This is on our list to visit this summer, most likely. My DS20 is also interested in CS. He doesn’t have a very open mind as it is (UIUC is his top choice at this point which of course is awesome, although we haven’t done many visits yet, because we’re in-state and he is assuming some close friends will end up there, but in different majors). I truly do hope CMU gets their act together. How disappointing for you!
