He mentioned to his Mom that he got to leave class for a couple of hours. He viewed it entirely as playing games and doing some mind tricks -- he didn't think of it as a test at all, so is none the wiser -- for now.
In terms of differing abilities, in our discussions I've often used the "all brains are different" approach as well, and he's fine with that. He's also met people (& is related to some) that are top-notch sports people or music people. Additionally, we have a SDD relative and an employee w/DS, so he is close to people of all different skills & abilities.
We've had a few issues with him bragging about his brain, but given the number of times he hears people say, "Oooh, you're soo smart," I can understand him feeding off of that once in awhile. But, in general, such bragging is verboten, and he knows it. (He's always free to brag around us, though!)
The challenge is when adults (who should know better) ask him, "You're really smart, aren't you?" Sometimes it rhetorical, but other times they stand there, waiting for an answer. There's just no easy way out of this one. We've tried showing a little modesty with "I do okay, but you should see my sister!" or a similar deflection.
