Well-organized, no-nonsense course with plenty of resources for practice and mastery of pre-calculus. Helped me greatly in dusting off skills I had not used since high school.

Love it, I just wish that they would combine it with the trigonometry course. The only gripe I have is that it is too simple, I completed the entire course in 4-5 days!
