800score (a free site similar to Khan Academy), has helped millions of students prepare for the SAT, GMAT, GRE, and LSAT since 1999. 800score GMAT and GRE simulation software has been licensed to test prep companies and universities, worldwide. The new digital SAT resembles the GRE and GMAT.
I studied neurobiology at Cornell, English at Oxford, and at Cornell Law. I scored a 99.98 percentile on the SAT. The median SAT score of my 250+ in-person students is 1480 (on par with Johns Hopkins and Cornell) with a score increase of +150 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. I worked with Ron Purewal (who holds the world record for most perfect scores on standardized tests) and a former Chairman of the College Board. 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. This suggests that ramping up college readiness will “ping” the SAT’s sophisticated psychometrics, resulting in a higher score with the added benefit of improved college performance. Simply put: If the SAT wants to measure college readiness, why not give the test what it wants?
To prep students for SAT verbal, I teach a crash course in college-level reasoning: economics, literature, philosophy, science, and logic. 800score has been simplifying complex intellectual concepts for 24 years. SAT prep done properly should help you get into your ideal school and succeed once there.
