My kid didn't get to take an SAT/ACT due to Covid. They did end up with a substantially lower PSAT score due to one of those dumb mistakes. They missed one "easy" question on the math portion while nailing almost everything else. The difference between National Merit Scholar Finalist and a "really good score".

They're doing great at a top 50 university now but it probably was the difference between waitlist and admit at two top 15 schools.
