Which option is better?? 31.3.4.5 to 2 or 41.3.5 to 9?

Hello, I have a bit of a dilemma.... my son has been struggling for a while with friendships at his current school, not getting the best grades and I think feeling quite lonely at times. He got in trouble recently and received two detentions, which resulted in even more isolation . He has been placed in a different class next year, which I fear will make things worse. I asked the Yi:
What if I keep my son at J? 31.3.4.5 to 2
What if I move him to K? 41.3.5 to 9

I’m actually non the wiser! What do you guys think??
