Thanks. He is a junior. I’d switch the question why *would * you take an exam that offers little to no benefit?
For example, he isn’t taking the PSAT this year as for him there’s no benefit. He’s already taken the SAT and clearly won’t be a National Merit Finalist, so why would he spend a morning in a stressful exam?
Going to that rigorous prep school with some big extracurriculars, I try to remove stress/work if they aren’t necessary.
