The middle one is in the same two-years-accelerated gifted track as the younger one. I think it does give him comfort that there is some outside confirmation of his intelligence, but the classes themselves are kind of problematic because he's definitely in the lower half or even quarter of his classes (except math), so he also has all his classmates to compare himself negatively to. (He has really obvious slow processing speed -- like, if anyone didn't believe it was a thing, they could just spend 5 minutes with him! We talk a lot about that too!)
