If you thought that paying a couple of hundred dollars for an hour of SAT/ACT tutoring for your child was outrageous, get this: A tutor named Anthony Green charges $1,500 for 90 minutes — and he insists that customers take a minimum of 14 sessions, all online. Why? Because rich people will pay, and because he believes he is just that good.

Business Insider writes in this story about a 26-year-old named Anthony Green who lives in New York and says on his company’s Web site, Test Prep Authority:

After working with more than 350 students one-on-one, and more than 10,000 hours of hands-on experience with the SAT and ACT, I’ve crafted test prep and college strategies more effective than those of any tutor, program, or class in the world.

Did you get that? In the world!

The SAT/ACT test prep industry has been booming for years, with tutors commonly charging several hundred dollars an hour. Some have been charging well over $500 an hour, and $1,200 workshops have been filled with students. But Green has raised the financial stakes. He charges $1,500 for 90 minutes of online tutoring, and he requires 14 sessions, which is $21,000.

His promise: He can raise a student’s score on the PSAT and raise the score on the actual SAT an average of more than 430 points (or an average of more than 380 points, depending on where you are reading on his Web site) and 7.8 points on the ACT. The PSAT, formally called the Preliminary SAT/National Merit Scholarship Qualifying Test, is generally taken in a high school student’s sophomore year and is considered a practice test, except among those who try very hard because they are hoping to get a National Merit Scholarship (which are given to students based on their PSAT scores).

Test prep professionals have told me in the past that it isn’t hard to raise PSAT scores significantly among the large population of kids who barely tried because there are no actual stakes to the result.

So is this a gimmick? What do you think?
