I suppose that this Google result I recently stumbled upon while doing some SEO research is a good sign for business. (I'm referring to the "People also search for" suggestion on the bottom right.)
Hey, I'll take it. After 20+ years spent working full-time as a private tutor and classroom instructor, and multiple perfect 2400 / 1600 scores earned by my students, I'm not afraid to claim—and embrace—the mantle of best SAT tutor in the world.
By the way, I also tutor the LSAT, GMAT, GRE, ISEE, SSAT, and ACT, and I'm among the best in the world at those subjects, too.
