And BTW, if you expose your average ND (normal devlopment) pre-K to 2nd grade child to physics and math, they will not pick up on most of it. So if you expose a child to it and they get it, it's GTness.
GTness is not about *what* a child knows, its about *how* they learn: and in general terms that's quickly, with a greater depth of understanding, with less repetition of concepts, and with greater joy than an ND child. If your child is a learning machine and you can't keep up with his drive to learn, or if he's obsessed with a topic to the point that he probably knows more than some (adult) experts in the field, it's GTness.
