The Cool Math Guy Precalculus Course (formerly Chalk Dust) is a comprehensive, college-preparatory program that combines the full scope of College Algebra and Trigonometry, along with additional advanced topics. It is ideal for students preparing for Calculus or for college-level placement exams.
Key features of this course include:
A complete and integrated curriculum covering algebraic functions, trigonometry, vectors, conic sections, logarithms, and more
Extensive use of graphing calculator techniques throughout the course
A strong academic foundation that prepares students for success in Calculus and beyond
Note: Because Precalculus includes all topics from both College Algebra and Trigonometry, it is not necessary to take those courses separately. However, Cool Math Guy does offer both as stand-alone courses, and some homeschool families prefer to complete them individually at a slower pace. If you are considering that option, feel free to contact Cool Math Guy for guidance.
The student begins by watching a video lesson, then starts the corresponding textbook assignment the same day, working until their scheduled math time ends.
The next day, the student continues the assignment until it is completed or time runs out. A third day may be needed—and that’s okay.
On the following day, the student moves on to the next section.
After completing several sections—or at the end of a chapter—the student takes a practice test and checks their answers using the provided key. Parents may assist in this process.
Once ready, the student takes the chapter test under parent supervision. Test keys include point values for grading. If there are any grading questions, contact Cool Math Guy—we’re happy to help.
If students or parents encounter difficulties, support is available through multiple methods:
We understand that questions can come up, especially in the beginning. Personal support is available via text, email, or phone. We’re here to help both parents and students every step of the way.

Note: This is a very robust Precalculus program. Some sections—and the final chapter—are intentionally omitted, as they are typically reviewed in the first days of a Calculus 1 course. Assignment lists will reflect these omissions.
Even with some content skipped, the course may take up to 10 months to complete. That’s normal—most schools don’t finish every section in a single year. If time becomes tight, you may safely omit additional sections without compromising the integrity of the course.
Also: We suggest completing Section 4.3 before Section 4.2 for improved learning flow.
