We just got my 7 year old's WISC V score report and the interpretation of the psych is essentially that he is gifted. There seems to my uneducated perspective to be a pretty big spread in his scores. She didn't calculate GAI, which I would like to know if it is helpful.

Can someone help me understand what these scores mean? I'm not sure how to make heads or tails of them. 42nd percentile for working memory and 18th percentile for processing speed seem like red flags. Does this suggest a second E? Please help me understand.
