The market approach, acumen and technical details presented on this site aren't much different than senior or graduate level science courses in college. If you're to get maximum benefit, you've got to know the material.
A good example of this was an experience I had years ago. I was an upper class-men engineering student at Texas A&M. I had made it through years of study and could just about see my way to graduation. That was until my Automatic Control Systems class.
It became clear at that point, I really didn't know much at all. There was still a long way to go. My visions of great accomplishment were dashed. All I had really managed to do was survive the typical weed-out of lesser students.
