Welcome!
These are very nice scores, generally speaking, with the exception of the QR and WM sections. Even if he wasn't interested in QR, I would be cautious about interpreting all of that as noncompliance/lack of effort, as that is two separate subtests, with multiple sections, that he did lower on than the other composite areas. And the two subtests are quite consistent with each other. So it could be real, or not. In addition, the other area with weakness is WM. Of the five composite areas assessed, the two which are usually most closely associated with mathematical achievement are QR and WM. But of course, that's not absolute, either.
Beyond that, you would need additional information, including academic achievement, to assess 2e. Are there IRL concerns that led you to this testing?
