> Personal tutoring for standardized tests has diminishing returns compared to just grinding...

Eh, not so sure. My son got a 32 on the ACT the first time he took it, and after 4 months of private tutoring got a 35, with 36 on math. Could he have grinded himself and got there? Possibly, but I doubt it. Having someone who knows what they're doing and holding him accountable was invaluable.

You know your son well enough to say he wouldn't have done the grind by himself. But that's not the same as proving that coaching is always superior to grinding. Or that a motivated grinder can't beat a less motivated tutored student.
