Khan Academy

Put your thinking caps on, because this website is gonna educate the $#17 out of you.

Directly from the website:

"The Khan Academy is an organization on a mission. We're a not-for-profit with the goal of changing education for the better by providing a free world-class education to anyone anywhere.

All of the site's resources are available to anyone. It doesn't matter if you are a student, teacher, home-schooler, principal, adult returning to the classroom after 20 years, or a friendly alien just trying to get a leg up in earthly biology. The Khan Academy's materials and resources are available to you completely free of charge."

This site has over 2,700 educational videos covering a variety of topics, 290 practice exercises for you to complete, and even rewards you with badges and points (useless as far as I know but satisfying nonetheless) depending on what you accomplish on the site. There are also other statistical graphs that track the subjects you learn about that you can view.

This is personally one of the noblest efforts I've ever seen directed towards the benefit of humanity, and if we had a world full of people like Salman Khan then we'd be in really good shape. My thanks go out to him and everyone involved in the creation and daily improvement of the website.
