Our Founders

We were fed up with expensive PSAT prep classes and mediocre teaching. We figured out how to master the PSAT, and we created PrepScholar to share our strategies with you.

Allen Cheng got perfect scores on both the SAT and ACT and leads product design and teaching at PrepScholar. From his own teaching and educational career, Allen noticed how most education, especially test prep, is too one-size-fits-all to be effective. He co-founded PrepScholar to bring you the same approach that’s worked for him — find your weak points and master them with focused practice. Allen loves product design and is passionate about creating the best user experience for PrepScholar users. Allen graduated summa cum laude from Harvard University, where he earned multiple teaching awards.

Fred Zhang got a perfect score on the SAT, was a National Merit Finalist, scored in the 99th percentile on the ACT, and leads customer outreach and marketing at PrepScholar. Fred mastered the tests by dissecting the test, focusing on his weak spots, and consuming every training material he could find. Fred is passionate about connecting with the PrepScholar user community and using your feedback to improve our product constantly. He also designed the advanced algorithms that pinpoint your weaknesses and tailor your educational program for you. Fred graduated from Harvard University with a Bachelor’s in Mathematics and PhD in Economics.

Since all the lessons are divided up into individualized sections, I can clearly analyze and fix any weakness or insecurities.
