Thanks for this insight @tiny_teapot . Is your son engineering? My son will be finishing Differential Equations and Physics 2 as Dual Enrollment. I understand Case giving him the option to retake any of these courses, but I can’t imagine them requiring it. Or putting him into the next level of math as a substitute option.
We homeschool - there are not “graduation requirements”. We graduate him when we want to graduate him and he’ll essentially have about 8 math credits and 8 science credits so the DE used for HS requirements isn’t clear to me.
