Behavior of University Students

I really don't understand what is the purpose of student entering universities nowadays........

• ask friends to sign their attendance when they absent for lecture class
• talking/study other subject/do other works when lecture teach in front/during lecture class
• leave the class(go back) during break time in lecture class
• copying tutorial works/during exams

These are the attitudes I observed since I entered university.....It happens to students regardless they are first, second, third or final year students...........

If me; as a student/friend also can't stand with this kind of attitude, what else about lecturer?
They too have feelings!!!!!!!!!!

I quite angry sometimes when they don't pay attention during lecture and then when exams is near only they busy asking for notes, what lecturer teach, ask this and that, telling that they don't understand...........

It is quite irritating sometimes because I also need to study ma............
