In my son's HGT class (2 grade levels), I think there are 3 PG kids including him. I think my son is sensitive, disorganized, but typical. The other boy is 2E and I think a typical active boy. The 3rd PG child has ODD. He has been a handful for teachers since 1st grade, and a challenge for other students as well. He apparently has friends now, but I know the early grades were tough, as he seemed to purposely do shocking things that landed him in the principal's office several times a week, and expelled 2-3 times a year.
