Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. 

Courses are offered in math, science, computing, history, art history, economics, and more, including K-14 and test preparation (SAT, Praxis, LSAT) content. Students practice at their own pace, first filling in gaps in their understanding and then accelerating their learning.
