Hi, LotsOtots5
I mostly lurk around, but I wanted to reply here:)
It could be that he truly is bored, because the pull out classes aren't always terribly challenging. Also, they may not be working on a topic he enjoys. When my son attended, they spent a month on some LA topic ("gag") followed by a month on astronomy ("cool"). Perhaps they'll be moving on to a new topic soon. Maybe the teacher could give you some insight into what they'll be covering, and you can use that info. to encourage your DS to hang tough. The teacher can be a great source of information. She may get defensive if you jump right in with "he's bored". I would tell her that your son seems unhappy with his new class, then try to learn more about the curriculum and the class dynamics. With more information, you will be better informed and better able to ascertain the true nature of the problem.
It could be that he is lonely and overwhelmed by all the new faces. Speaking as an introvert, one of those weirdos who would rather go to the library than a party, this can be a major turn-off! Again, if he can hang tough just a little while longer, those new faces will become familiar.
When my ds 10 says that he is bored, there is often something else going on.
Good luck
