Khan Academy?

[garya73]

Anyone take any classes on Khan Academy (www.khanacademy.org)? I just learned about it today.

The classes are free.

I could really use a refresher on advanced math, i stunk at precalculus and calculus. One of the major reasons why I dropped out of the computer science major when I was in college (1990's). Also because I disliked programming. And they weren't even using C. It was frustrating.

Go for it.

Definitely found Khan Academy videos useful when I was taking calculus my freshman year of college. They were a good supplement and actually helped me understand the material, something my professors didn't really do. However, I've never used it on its own to try to teach myself something, but there's no harm in trying if you're interested.

I haven't used Khan, but I did check out Coursera, and I think they're similar models. It was pretty good stuff.

Khan is awesome. Watched his youtube videos for linear algebra...really helped to clear up the mess of a text book we had.

Used them when I had to do organic chemistry 2 years ago. Life saver.
