About

Calculus Primer is a student-led project dedicated to promoting higher education in physics and mathematics by providing free, high-quality calculus learning resources required for higher math and physics. We pride ourselves in the quality of our expert-written handouts, which cover 21 separate topics ranging from derivatives to differential equations. Our goal is to provide quality learning materials to aspiring students around the world especially interested in the Physics Olympiad, filling the gap created by the lack of resources online for the calculus prerequisites, enabling students to safety dive into the intricate world of physics.
