Nowadays, the society has been increasingly strictly require people to acquire more abilities for the fact that the competition is getting more intense. Therefore, to make sure their students have comprehensive skills, it is obvious that the universities should require every student to take a variety of courses outside the student's field of study.    To be useful to the society, a student needs many abilities which are not accessible only inside the student's field of study. To be successful,  a student should be healthy first, but the knowledge and methods of avoiding sickness cannot be learned from a Math book. What a engineering majored student study in classroom are subjected courses such as Theoretical Mechanics, Material Mechanics and Engineering Drawing, etc. Non of them could make us healthy. However, a student could learn how to play football and basketball from PE courses and how to build a good body from health protection courses. Second, a good social circle is important for a student to be successful. You won't start a conversation with a girl with the great Goldbach's Conjecture. Take a enjoyable movie or music will be obviously better and that's why you may need to take course about Beethoven and Haydn.    Taking courses outside where the student majored in is helpful and beneficial. To be a successful scholar, a student should master how to write a good dissertation and obtain information fast and correctly. Taking writing courses and language course could help a lot.    Admittedly, taking courses outside the student's field of study may take some leisure time and affect the major study. However, the students will acquire many other skills from these courses which will be very beneficial in the future.So it's worthy taking the universities should require every student to take a variety of courses outside the student's field of study.
