I can only answer from my experience - my son is 7 (June birthday), in 2nd grade - and goes to 3rd grade 4 times a week for math. He got 96% in 3rd grade this 1st quarter, and is placed in a group of 4 at the "top" of the class. I think there are about 60 kids in 2nd grade, and he is way above any of them. So - yes, in his school, he is "unusual" smile Fortunately, the school recognised that last year, and have been wonderful at helping him out.
