High School Pre-Calculus Course

Time4Learning offers an online, interactive high school curriculum that correlates to state standards. It can be used as a primary homeschool curriculum, a supplement to your current curriculum and as an afterschool or summer skill building program. At the high school level, Time4Learning is organized by courses rather than grade levels, so parents have the option of choosing any four as part of membership.

The Pre-Calculus curriculum is one of five Math courses offered at the high school level. AP Calculus is taught using a combination of multimedia lessons, instructional videos, worksheets, quizzes, tests and both online and offline projects.
