About

My company, 800score (a free site similar to Khan Academy), has helped millions of students prepare for the SAT, GMAT, GRE, and LSAT. 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 scored a 99.98 percentile, cumulative, on the SAT, and 99th percentiles on the GMAT, GRE, and LSAT. The median SAT score of my 250+ in-person students is 1480.

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. I have taught the new Digital SAT and have years of experience with computerized testing.

I offer a 250 point score increase/or over 1450 guarantee.

I only accept serious students:

> a commitment of at least 100 hours of intensive self-study.

> coachable and willing to accept feedback to self-improve.

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.

    Sean does a great job of simplifying content (Feynman method) and teaching students “how to teach themselves how to think.” Just completely remarkable and life changing. My son’s score shot up 330 points and his confidence is night and day. The whole SAT experience turned into a positive one.

    I highly recommend Sean as a SAT tutor for anyone wanting to get the highest score. He is a ridiculously talented tutor and is always prepared for our sessions. He completely understands the exam and always provides useful advice that was very helpful in my preparations. On top of that, he also has great teaching methods which helped me grasp concepts effectively and efficiently!

    Sean is the best teacher I’ve ever had. I wanted to go up from my prior score of 1520 and he raised it to a 1570.
