That reminds me of DD's friend--she also did not do well on the CogAT (composite score 121 I think). She could do long division in first grade but scored in around the 75th percentile on the quantitative CogAT because she also did not finish. The questions she did answer were all correct. The father told her to be careful and check her work which is what I told DD (not knowing it was timed). Ridiculous!
