When students take a variety of course outside their own field of study, it is not denial that those student will have more knowledge than before. Learning more knowledge or having wilder range of vision, those students will have more deeply insightful thought and variety methods of dealing problems so that those students will have better professional performance of their own fields. For example, if a students whose fields is chemistry and learns literary as his outside course, he can write article about some hot topics of his own fields which normal considered it but cannot fathom it, such as chemical gradient added to food or poly-material, in a terse and perceptible way. In this manner, his article can be easily accepted and by those people whose field is nothing to chemistry even those are ignorance, It is not only great academic performance for that students but also a convenience for those normal people. On the other hand, taking a variety of outside course, students can hone their social skills. When they go to the various courses outside themselves field of study, they will know more friends than those people only take course inside his fields of study. After graduation, students who take eclectic course outside their field of study can be more equolent when talk to people whose field of study is relate to the outside course compared to the students who only learn the knowledge about his field of study.   However, a variety of course may not apt to every students. Some students only interested the field of study that he has already choosed. For students like that, they may not want to waste their time on the courses which is not relevant to their field of study, they prefer to learn the knowledge of their own field or do some research of that field. Moreover, in today's world, amount of elites are such person with fully preoccupation of his own field. For example, Ono jiro, almost the most famous cooker in Japan, has pinpointed on sushi for over 55 years without abstacted by other non-relate things. Sushi is the field of study for Ono Jiro, and he is the oldest cooker of Mcihelin Three-star Restaurant. Alternatively, for some students, learning the knowledge of his majority is burdensome drudge for him, taking a variety of course outside his field of study will be the last straw that drives him fraughtful. Considering different level of learning ability and assorted interest, Students should have their freedom on whether they take those various course outside their field of study.   As for University, setting those various course is indeedly benefitul for some students, however, if the university does not have the ability to arrange those various course outside the student's field of study, than setting those outside course may obstacle development of university. For example, if the whole faculty of a university are just enough to inside field course, taking a variety of course outside field will require those professor work more assiduously. If faculty cannot endure those demanding work and then resigned jobs or working derelictly, this university cannot profer education with good quality or enough teachers to their students. On the other hand, if a university cannot fund for outside course , in this manner, taking that outside course may cause finicial crisis for that university and may be finally casue the university to bankrupt.   University should consider their condition of taking that course outisde the student's field of study, and it is not necessary to require every student take the course outside their field of study. Student should have the right of whether to go that course outside to his field of study and how many outside course that he want to take.
