It could be the 90th percentile of science and the 60th percentile of literature and the 40th percentile of music. But if they throw you in with the 50th percentile kids in all cases then you're being held back in science and literature and you're holding back the other kids in music.

This is why home school families come together so their kids can socialize with one another.
