where just following the conversation is a problem, while they are outright bored with the highest difficulty technical AP classes available, because they find them very easy.

Then accommodations should not be needed if they are so easy, unless I am missing something?

Accommodations don't have to be used in all classes. They might need accommodations in an English class and no accommodations in the scientific or math classes. Usually this isn't evaluated per class, it's evaluated per student and then it's up to the student to use or not use the accommodations for the various classes they take.
