He's not yet 4 and I put him for K. He passed the only pre-test he's done so far, and his error rate is prob c. 0.25/set
(mostly in groups of 2-3) He's done 1/4 of K in those 3 hrs.

I kinda think it's just that slow... maybe it'll pick up once they give him more pretests?

DS1: Hon, you already finished your homework
DS2: Quit it with the protesting already!
