In what setting does Ben feel most out of place in the novel, What If It’s Us?

A hotbed of tension, Ben's classroom for summer school is difficult to navigate every day. Ben sits in the back because Harriett and Hudson sit in the front, and he doesn't want a conflict to occur again with them. This is the place where Ben feels most out of place, and he does worse in the subject material than he estimates almost every time there's a quiz. Just outside the building is where Ben and Arthur break up, when Hudson comes running out.
