As the AP Calculus teacher at Kinnelon High School, Mr. Petrucelli is known as the ace in one of the most difficult subjects in all of mathematics. Nevertheless, Mr. Petrucelli has become an expert in all of the mathematics that lead up to calculus: algebra, geometry, and pre-calculus. Well into his second decade of teaching, Mr. Petrucelli has hit his “10,000” and can easily solve even the most difficult of problems with his tutors. As a result, he is one of our most popular tutors, often employing his expertise in teaching the SAT and ACT.
