Forget "IQ" for a second, because the word has too much baggage. Let's talk about learning ability, which is normally distributed and which IQ captures well but not perfectly.

Starting at age 25, a person two standard deviations above average in learning ability wants to learn mathematics from high school algebra to advanced college level, working 15 hours a week, every week, toward that goal. How long does it take them?

How much faster will a +3SD person learn? What about +4SD or higher? What are the actual measurable differences in learning ability at the tails?

If you have extraordinary learning ability, don't be afraid to share your experiences. I'm curious.
