friend classmate or other ?

today when i study in university college, i feel somethings wrong with my class.
when i have the PDSM class i know that the class will end early,
but the things i dislike is the classmate are not pay attention during the class.
even though this is not subject that we need it like mathematic or business.
we have paid it, we have paid the module fee, the university college need us study it.
that is the reason we study it, and some of us are need the concentration in the class.
they need the study environment
please help the other.
and one of them, i very dislike his attitude, and feel that
are he/she still human being just say someone like this !
