Homeschooled with MIT courses at 5, accepted to MIT at 15
Even with all the positive support from parents this kid is an extreme outlier.<p>Terrence Tao supposedly knew numbers from Sesame Street at age 2, but I do not know of any avid kid readers at age 2.<p>I know plenty of kids ages 3-4 who know the alphabet but none are actual readers.<p>In fact I know plenty of kids who "read" a book at age 3, but they are not reading the way we adults are they are imitating the reading process.<p>Anecdotally I was a relatively early reader at age 5 (reading whole scary Grimm's tales) but my mom keeps insisting it was age 3 when I know it was not.<p>So if he really was reading at age 2 and half that is showing   advanced potential.
