Do you know why your son’s grades in STEM fields are what they are? I normally wouldn’t ask, but if he has a 36 on Math and a 36 on Science on the ACT, then it’s surprising that a B is predicted for precalc this year, and that he’s had Bs and Cs in both math and science.
I think that figuring out the answer is important in terms of being successful in college. Does he have executive function issues? Or a learning disability? Or…? From what I’ve heard repeatedly, the engineering curriculum is a doozie, and you would want to make sure he’s in an environment with all appropriate supports (whether he gets supports in college or needs to learn additional study/academic skills before graduating from high school).
By the way, have you thought about U. of Louisville? I’ve heard some very good things about its engineering program.
