If you are like many students, you are furiously copying notes during class and not really comprehending what is being taught. Then you try to teach the material to yourself from your notes. This takes a lot of time.

When you use the Khanacademy before you do your homework, you are more likely to absorb what is being taught. A ten minute video can save a lot of time trying to figure out how to do a problem.

One of the advantages of the Khanacademy videos is that you can pause them, go backwards, or go forwards. You can learn at a pace that works for you.

The Khanacademy also has practice problems that you can use to evaluate your comprehension of the material. This is a good way to study for tests.
