At Math Prep Books and Richard Corn LLC, our mission is to produce math books that students actually benefit from using in the real world. This means books that raise math grades in school and raise scores on standardized tests like the SAT® and ACT ® . More than 45,000 copies have been sold.

Our books are written by high school math educators. Before they are published, they are field tested by real students. Every edition of every book reflects improvements made because of their feedback.
