How long to complete Calculus 1 on Khan Academy?

Hi Adam,

The Calculus 1 course currently has 367 videos with a total runtime of about 37 hours. So at minimum it would take 37 hours just to watch all of the video content.

There's also many exercises that go along with the videos, so you will need to factor that into your schedule as well. The time to complete the exercises, quizzes, and unit tests greatly varies depending on the student, so I can't provide an estimate for how long those might take to complete.

I hope this helps!
