When DS went up to 8th (from 6th) for the first year of the HS math sequence, there was definitely resentment. At parent night, an 8th grader came up to me and said, "I hate your son." I asked why and she said because she works so hard to understand the teacher and get the work done while DS just walks in from 6th grade and gets A's. She had a smile on her face. And I said, "Yeah, I know what you mean. Some days I feel like that, too. And I'm his mother." Then we laughed. She never gave him any trouble, but I know it was discouraging for her to try so hard and not be as smart as a kid 2 years younger. I would guess she is not alone.
DS has been very careful about letting kids know what grade he is in now that he goes to the high school for math. It got out just around the quarter and, by then they already knew him, so by then it wasn't a big deal.
