Should students take all the courses regardless of their branch?I think both departmental and nondepartmental courses are important for our education.Firstly,we should take the courses that are related to our department.In other words,they are some parts of our professional fields and we have to take these courses to make a good job.Furthermore,we should also take some courses that may not be related to our department.Because,a person can never be a real profession without knowing sth different from his or her field.A person should be sophisticated.But both departmental and nondepartmental courses should be selective.Students should be free to attend to the courses.And they should be free to elect the optional courses.And the students in nondepartmental courses shouldn’t be responsible for the exams.I think only in that way can students be happy and successful in the courses.
