About

My company, 800score (a free site similar to Khan Academy), has helped millions of students prepare for the SAT, GMAT, GRE, and LSAT since 1999. My GMAT and GRE simulation software has been licensed to test prep companies and universities, worldwide.

I studied neurobiology at Cornell and English at Oxford. I got the equivalent of a perfect score on today’s SAT math at age 13 and ended up with a 99.98 percentile, cumulative. I worked as a Wall St. Analyst and then started 800score to provide free test prep. The median SAT score of my 250+ in-person students is 1480 (on par with Johns Hopkins and Cornell) with a score increase of +120 on Verbal.

I've been to ETS and GMAC headquarters (where the SAT/GRE and GMAT are designed, respectively) and have consulted with their psychometricians. Kaplan wanted to hire me for their R&D department, and McGraw Hill offered me a publishing deal.

The SAT is used by admissions officers because it strongly correlates with undergraduate GPA. Ramping up college readiness will “ping” the SAT’s sophisticated psychometrics, resulting in a higher score with the added benefit of improved college performance. SAT prep should help you get into your ideal school and succeed once there.

    Thank you for your “pet policy”, “pet theory”, “galaxy brain”, “robot lawyer”, taoism and all your other brilliant insights that helped me kill the SAT.

    Sean mixes up a variety of strategies from Bruce Lee’s Taoism to neurobiology to Richard Feynman. I learned so much and was able to raise my score by 390 points.

    I had the pleasure of working with Sean as my SAT tutor. He was patient, knowledgeable, and always willing to go the extra mile to help me understand difficult concepts. His teaching style is engaging and he has a knack for breaking down complex topics into easy-to-understand chunks. I highly recommend him as an SAT tutor - hes the best!
