Question for Gordon Korman 2

So in this post (https://gordonkorman.com/forum?t=31024) you said that the Unteachables would be in different classes in high school (“next year”). However, Mr. Kermit said, once rehired, and I quote, “Sign me up for next year…and I want SCS-8. Nobody else.” So does he mean “I want to continue teaching the same class for the rest of the year”? I feel like he wouldn’t need to state that. I initially read it as “Sign me up for next year, and I want to teach the kids in SCS-8 next year.” Maybe I’m just confused, could you please explain?
