Personally speaking, I prefer professors make decisions. The main reason is professors’ choices tend to be mature and informed. They are clear about what students should learn and master for certain subjects. Taking the economics for example, professors have been investigating in this field for decades, they know students should learn courses like mathematics, econometrics, statistics, finance and so on, so as to master the skills needed in economics. However, if choosing by students, they are likely to be in a puzzle or at a loss about which courses to learn, consequently they may not learn necessary knowledge and achieve desired results.
