Very good point.
Well, that was mistake #1. While the OP did not provide a breakdown of the scores, it is nor unusual for a 13/14 year-old to score well on math and less well on EBRW. IMO, the skills/knowledge needed for the EBRW section are ones that come with age, not innate intelligence. Yes, I am sure that somebody knows a 13 yo who scored a 790 or 800 on that part, but they are the 1% of the 1%; for the vast majority of kids, this is something that improves exponentially over time.
