should it be compulsary for university students to attend the classes?

It is not binary, you do not have to choose to either go to class or think that the University is a huge amusement park (actually, most of the amusement parks I know are bigger than most of the Universities I know), there are other alternatives. Going to class is not the only way to learn. Actually, when you are an advanced student and you are on a basic class (for example, if you have previous experience on the matter), most of the other student's questions will be uninteresting to you and it can happen that attending a class is actually wasting your time (that you could use to learn something else, for example). I do not understand why some people think that the Academia is never wrong and that the way they think and say things should be done is the way things should be done, even when the justifications they give are often just something they are repeating somehow. Learning doesn't only occur inside of the classroom. Lots of people think it does and that is the reason why you have so many low-quality profesionals in almost every career.

Going to class teaches students how to work with other member of the class. Many times students will be given group works or assignments. This is different from what they did in secondary school. Here they are with people from different backgrounds and expeciences. In this situation, they learn how to handle working with people different from themselves to achieve a common goal. Going to the class also teaches students responsibility and discipline. Having to be at a particular place at a particular time prepares them for getting a job. Being at a place on time with an assignment completed prepares them for carrer.

Yes, if you want a job, that may be the right thing to do. As an entrepreneur, I do not like jobs and I would never hire someone for a "job". I have worked with other people in projects that we have developed but it was nothing like a job: we set out goals and achieved them. We did not need to make a commitment or even "be there in time". None of us needed to "learn responsibility and discipline" because just wanting to do what we were doing was enough to have everybody be responsible and do their part. It is easy to get to where you need to be on time, no need to "learn" to be responsible for 4 years. Now, I have learned a lot more about working in groups while actually working with people than by attending my classes. Less than 20% of the classes I have had had even 1 exercise or homework or anything to be done in a group. Most of the time you only have a teacher that talks about the class' subject and people asking questions, sometimes, the teacher just gives you some copies and reads them with you... Now, about the different "backgrounds", the truth is that, in the University, most people don't really have a "background" they just finished high school and they want to keep partying... but mainly, they just have different personalities but no real experience that you can learn from... most of the time (there are exceptions). Now, I am not saying that you shouldn't attend your classes but I do believe that making attendance compulsary will just make people learn to obey, follow the rules and take orders as well as learn to tolerate a routine... which are all activities that are contrary to creativity and will make people into good low-level employees... So yes, go to every class and if you just do it you will learn a lot of things. Still, I can personally do a better job at teaching myself than most schools can. For example, I have learned programming, 3D modelling and animation, hypnosis, piano, Italian and calculus, among other things by myself without ever taking one single class about those subjects.

I agree with you a 100%. Some schools make it more important that you attend all your classes than actually having learned something useful and use it for their students to pass. I do not want people who can be there on time all the time to work for me, I want people who can think for themselves and solve problems. Schools tend to presuppose that you cannot learn outside of the classroom but that is because education is an enormous business all in all.

checking of attendance is just for primary and middle school. they are adults and they know what they're doing. they know the consequences of their acts. some absentees are smarter than those who are always present,take it from my experience.

yea i agree with you.In short, by going to class students learn more than just information from the teacher. They also learn how to learn, how to work with others and how to work responsibly. These are not optional skills in life, so attending classes should not be optional in college.

It has happened to me to know the subject better than the teacher and yet be forced to take her class and do her simple and boring exercises and listen to her lousy explanation just because of the attendance requirements.
