Your son's scores are close to my son's(8 1/2) except his processing speed is 109 and his PRI and VCI are a bit higher. His processing speed significantly affects his ability to perform "on command" or to succeed on timed tests at his regular academic level. Other than that, we haven't found a problem with it. It's frustrating to him that he's stuck doing timed multiplication facts tests at the same time as he's doing Pre-Algebra. If he has time to be deep and thoughtful, his work is fabulous.
I would assume he rushes through his classwork because it's not challenging enough. If he has a really meaty problem how does he do? Multiple steps like a hard math problem, an essay or science research?
