The Khan Academy: An amazing free website to help students of almost any age.

I found this website and was amazed. It has lessons from this guy in everything from basic addition to advanced calculus and finance.

I think the way he explains things really makes it easy for a kid who might be struggling in school. I've been using to try to get ahead in a few
classes.

It is definitely worth looking at if you have children in school. Or even if your interested in learning about basic finance or various other topics.

Not to mention it will hopefully be able to improve the education of poor students in third world countries.

Best of all it's free.
