Ok, you are just wrong here. Evan is NOT homeschooled, he attends an alternate study school called Venture because he is so far ahead of his peers, he would be bored in a standard school. Although he was able to test out of high school at 12 years old, his parents insisted that he stay in school with his peers so that he wouldn't have the same social issues that most kids with his intelligence level possess.
Evan's parents have ensured that not only is he well adjusted, but he participates in all kinds of activities outside of his incredible level of intelligence. In addition to science, he was the national spelling bee champion, is an accomplished musician, and participates in all kinds of non-academic activities.
Evan lives near me, and I am friends with the Principal of his school (Venture), so unlike many who are simply making things up or guessing, these are facts.
Not only should we be impressed by his skills, but we should awed by his parents dedication to ensuring that Evan is not only given the opportunity for academic achievement (he recently got one of 200 early admission offers to Harvard), but is given the opportunity to be a "normal" kid and learn how to socialize instead of just being an academic...
