Khan Academy

All Kansas City Public Library locations will close at 5 p.m. on Wednesday, November 26, and will remain closed all day Thursday, November 27, for Thanksgiving.

The motto of Khan Academy is "learn almost anything for free", and their list of topics and tutorials just keeps on growing. Anyone, at any age, can sign up and start learning. With over 3,300+ video tutorials with complementary exercises, you learn what you want, when you want. The subject areas are math, science, finance & economics, humanities, test prep and, most recently, computer science.
