Some universities require students to take classes in many subjects. Other universities require students to specialize in one subject. Which one is better?

Nowadays, many people wonder whether or not university students should learn one subject or many subjects. Some of them say that studying one subject should be important for students, but I personally think that students should study more than one subject. There are many reasons why students should learn one subject. The first, they can save a lot of time. In fact, when students focus on only one major, they will have more time to finish their homework and assignments in a shorter time. The second, by attending in one subject, students have a chance to save a huge amount of money. Clearly, everything will cost a lot of money like books, materials so that if they work on one subject, they can save much money for their families. However, I believe that attending many subjects would be much more considered. Firstly, by learning many subjects, students can gain a lot of knowledge and widen their understanding about many different fields. For example, pupils who study science also understand about art or music. Secondly, students who graduated with many courses are likely to have better career in the future. In fact, when they work in various kinds of fields, they can select the most suitable job that they prefer. In conclusion, I think students should attend more subjects than only one. By considering both views, students can make the best decision for them.
