It is hard to deny that learning other subjects instead of the courses or major a university student chose would reduce the time the student spends on the major courses, and such a fact leads impressionable people to generate the opinion that students should pay full attention to their majors. However, such a statement suffers from both logical and factual fallacies, and it should be examined meticulously. As far as effectiveness, economy and feasibility are concerned, I strongly hold that students should spend time on other subjects in addition to their main subjects.
