The postgraduate entrance examination for dual-control majors is better than other exams, because there are many schools for dual-control majors and the threshold is low; After graduating from power system major, you can easily enter the power sector, and your work is relaxed and boring, much like a civil servant; Power electronics is closely related to enterprises, and wages are linked to your technical level; The scores and quality of different majors in different schools are different. I suggest that if you want to engage in theory and have a good working environment, you should apply for double control. The rest will be measured by yourself. Come on, professional quality depends on whether you like it or not.
