How was his working memory score on the WISC? I think that part of it may be that dd's working memory score was very high on the WISC, so her FSIQ was still pretty near gifted even with the speed part dragging it down. The SB5 has more of a visual memory subtest rather than an auditory memory subtest, so that may or may not be better for your son in that part.
his working memory index score was also not great at 99.. but not sure now whether or not this is auditory memory or visual memory that the WISC is measuring. Anyone know? He is notoriously bad with auditory processing..So this might be a big plus for the SB-5.. though he loves listening to books on tape which i think is really helping with that.
