is disciplines of students in college necessary

Pros:requiring class attendance in collage is necessary for students
College education is part of the education system in which regulations and disciplines are still necessary.With the class attendance,the class will be formal enough for students to take it seriously,moreover,on one hand it can partly prevent some students playing truancy,on the other hand,the teacher will have a clearer idea of the students he teaches,so for both students and teachers,class attendance will have a positive impact on the college education.
cons:atteding class in college is up to students
For a college student,he is old enough to know what is the best for him and then he will determine his learning priorities.Which class is essential to him,and which is not?Such questions will make him not attend the less important classes and have more time do what he thinks more important,later he might be very outstanding in certain subjects and establish a solid basis for future development.So if it is for personal development ,attending class in college is up to students themselves.
