Anybody heard of Khan Academy here? Its a great resource with plenty of well done video lessons. Its really helped me in my senior year of high school in chemistry and math. There's also a lot of information on a wide range of topics such as finance, physics, investing, and even venture capital. While you obviously don't want this to be your primary education, there's a lot of useful info at the site. The narrator is one of the best teachers I have ever heard and blows most of my teachers away.
