CR 740 - worth taking again?

My son got a 2300 SAT with CR the lowest score of 740. He is Math/Science kid not taking any English AP or SATII . He wants to take the SAT again to get the CR up but I don’t think it is necessary. His guidance counselor is ambivalent and not really helpful. On PSAT he had gotten a 75 on reading. Should he take the SAT again or just say “good enough”?

No, he is fine. Don’t waste time improving on this when it won’t make a difference.

It’s not necessary. Well done!
