Over the next six months, we will meet twice a week to go over everything you need to know about high school geometry to achieve a 100% score on the [Khan Academy Course Challenge](https://www.khanacademy.org/math/geometry/test/xff63fac4:course-challenge). In addition, we will have shorter review sessions on Wednesdays. Sessions are relatively slow-paced and often go overtime.

In this series, we will review functions by going through practice problems. Sessions are relatively slow-paced.
