Hi. How old is your child? And what was his experience of taking the math test? Thanks

also interested here. My son passed the math portion

Does anyone have any feedback on the Center for Talented Youth (CTY) at Johns Hopkins University, or other similar programs for gifted kids? I'd love to hear about your experience, how young your kid is/was, and whether/how it helped. My son is 8 and we're considering it. thanks.
