I have read quite a few times that the SB 5 favors those that are more math oriented where as the WISC IV favors those that are more verbal. Why is this?

I am just curious my child did the SB 5 and scored higher on the Verbal Sections and I wouldnt describe my child as mathsy, though my child is multiple year grade skipped in math.

So I am wondering, if I had my child tested on WISC, could I probably expect to see my dc do better? As my dc is more verbal or should it stay the same or maybe decrease?

Just curious.
