Looking for a reccomendation

[N/A N/A]

To preface this, let me say that I have taken college courses on microeconomics, macroeconomics, accounting, and basic business. I have a firm grasp of globalization and how wonderful capitalism is. However, I still feel extreemly uneducated when it comes to things like how the stock market really works, investment strategies, business law, taxes, etc. When I watch a movie like Wall Street, I cannot understand half the terms they are talking about, and I really want to. I want a good understanding of general economics in the real world to base my real estate education on top of. So what I am looking for is a great online resource (besides the forum environment) to help me learn. I can read wikipedia all day long, but I would like something that maybe starts from the beginning and adds advanced concepts as you go. Any ideas?
