I enjoy playing the math games at Khan Academy. I've been a member for over a year and have completed at least 300 of the exercises.
Now that I'm a grownup, I get to study what I want, how I want. I learn best when a concept has had a chance to stew in my brain. My favorite part of Khan Academy is how well I do on things that I didn't understand when I was studying them in school. It's a thrill to know the concepts have fallen into place in the meantime.
And, when I get stuck on something, I can review. For instance, in Statistics, I didn't understand the difference between mu and x-bar and the significance of standard deviations. After watching Khan Academy videos and doing the exercises, these finally make sense.
The Khan Academy exercises are meant for elementary school students, so they don't spend much time in Pre-Calculus and Calculus. But, I would love it if they fleshed these sections out and added some Linear Algebra exercises.
