I would reckon that the Median Kid would very much be able to get to the same level, educationally, as the 90th percentile kid. It may just take a little bit more effort on his part. This is because Education, in the sense of GCSE, A levels, and Degree, is not mostly about what you have been taught, and your ability to spurt it out in exams. Therefore, the better the teacher, the better you are going to do.
However, if you take someone with an low IQ, and someone with a high IQ, and asked them to do tasks which are similar to the ones used on IQ tests, then you would spot a difference. The difference here is that IQ is much more hard wired into the brain (as far as my biology A level can tell me), you wont be able to change that with any amount of teaching.
It just goes back the the gene and meme theory.
@ Pitt - Good point, I forgot about that, you may well be right with Tennis.
Also, thanks for the OP love
