I don't disagree.

Math is the real challenge though. When I was in business school I tutored a group of students who were... struggling. They simply lacked the ability to handle things like basic graphs in economics, solving equations, never mind the most simple differentiation to find a maxima/minima. It was a frustrating experience. I couldn't make up for a general lack of even high school math.

And read any number of books out there on first year bschool experiences and you'll find similar.

There are absolutely successful people who are in that category. But Math is a major roadblock for many people.
