Prep Expert is a test-preparation company that offers 6-week online and in- person SAT and ACT prep classes. There’s a reason Prep Expert founder Shaan Patel closed an investment deal with billionaire Mark Cuban on ABC’s primetime TV Shark Tank. We teach students 100 strategies Shaan developed himself to improve his own SAT score from average to perfect. We offer double the course hours at half the price with top instructors. We also offer the best score guarantees in the industry: if your child does not improve his or her score by at least 200 points on the SAT (or 4 points on the ACT) after completing our 6-week course, you get your money back!
