Precalculus

This course, which covers the fundamentals taught in a first-semester calculus course, will provide you with an understanding of functions and their properties. Our goal as creators of this course is to prepare you to pass the College Board’s CLEP examination and obtain college credit for free. “Precalculus is a transitional course. There is a big difference between life before and after calculus, and I want to prepare you as much as possible for this fascinating subject. The precalculus CLEP exam will require us to study algebra and function theory in great detail. A huge emphasis is also placed on trigonometry,” explains Dr. James Murphy, professor at Johns Hopkins University and instructor of this course. “Precalculus” is a completely self-paced course. It has no prerequisites and it is offered entirely for free.
