I started reading at age 4, was reading on a 12th grade level when I was 9.
I did well in all subjects except math - failed algebra two years in a row. Dropped out of school as a result. My college boyfriend had the exact same profile. I believe that there are some people who simply cannot think this way - it has nothing to do with intelligence.
I certainly agree it has nothing to do with intelligence. It is just the vagaries of the individual brains and the way they learn. That is why we are individuals and not clones...viva la differance!
