I made $1,000 an hour as an SAT tutor. My students did better without me

"Few understand that the SAT requires specific, school-independent training."

I took both PSAT and SAT cold with no specific preparation and did very well. So did my friends. It was even fun.

While I see no _need_ for SAT tutoring, especially for excellent students, I've heard claims that tutoring can raise scores. I would have felt, at the time I took the SAT (and even today, somewhat), that "preparing" was a form of cheating, since those who "prepare" have an unfair advantage over those who did not. It also taints the statistics.

But that was before I read about how physics and mathematics students in the English university systems were sometimes heavily tutored prior to mathematics/physics contests/exams. Having a personal tutor of Nobel-prize quality who drives you hard would undoubtedly sharpen one's skills.
