About

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. In addition, we will have shorter review sessions on Wednesdays.
Sessions are relatively slow-paced and often go overtime.
