My DS7 has took the DAS II score last summer. Originally I though it was pretty cut and dry, but now I find I have some questions.

His scores were
Verbal 140
Non Verbal 126
Spatial 118
GCA 135
Working memory 113
Processing speed 104

My questions come up with 2 of the sub-groups, Verbal and non verbal.
t-score percentile
Verbal Similarities 83 >99
Word definitions 65 93
Matrices 56 73
Sequential and Quantitative Reasoning
77 >99
I wonder exactly what the greater than 99 percentile means. Does it mean that there is no further differentiation, so it could be 99.1 or 99.5 percentile?
Why would there be such a gap between Matrices and S&Q reasoning?

Thanks, Rocky
