Meet Shaan Patel


I grew up in my parents’ urban motel, attended inner-city public schools in the worst school district in the nation with a 40% dropout rate, and was clueless about standardized tests. But through focused preparation, I was able to raise my SAT score from average to perfect — which changed my life! I was admitted into prestigious universities, won a quarter-million dollars in scholarships, and even got to meet the President of the United States. I was also a National Merit Scholar, a Coca-Cola Scholar, a Toyota Scholar, and on the USA Today All-USA High School Academic Team.

Now, I’ve created Prep Expert (Formerly 2400 Expert) to help other students achieve their dreams! Prep Expert is the nation’s fastest growing test preparation provider. We offer 6-week SAT & ACT preparation classes in 20 cities around the country and online — some are even taught by me! Many of our students have gotten into the Ivy League, won millions in scholarships, and some have even gotten perfect SAT/ACT scores themselves.

I am currently an MD/MBA student at Yale & USC. I’ve published nearly 10 books, including some #1 bestsellers on Amazon for SAT & ACT Prep and just published my first self-improvement book Self-Made Success. I also recently appeared on ABC’s Shark Tank and closed a deal with billionaire Mark Cuban. You can watch the episode here.
