Provide the theme summaries for the following conversation: 

Mike: I kinda forgot to sign up for Thursday morning classes 
Caroline: You don't need too
Mike: wtf? how come?
Hannah: they do that for us, Dean's office
Mike: That's new. Know why?
Hannah: There's just 12 of us now, it's just easier for them to make us a ready made plan
Mike: That's cool, nothing to worry about 
Caroline: Yeah, and no choice, there is too little of us, they're just gonna sign us up for those classes that are left with places

Summary: 
Dean's office is going to sign Mike up for classes. It is more convenient for the office as the group is only 12 students.
