I’d say that you are in good shape. Johns Hopkins tends to be positively inclined to those who did the CTY-can’t tell if you just got a high score or actually participated in their stuff. If just high score in years before high school, that is different. Your activities before high school really should not be listed and won’t be considered. If you did CTY then Hopkins is probable but if you just won a certificate for a high test score, then I’d say Penn and Hopkins will be a stretch but you seem in good shape for the others, Cornell if you apply ED.
