The level of the school is the first aspect of the application, but the strength of Jiaotong University and Zhejiang University is similar, so this is not important. However, it should be noted that Zhejiang University is comprehensive in arts and sciences, and natural science and social science keep pace, while Jiaotong University is slightly weak in arts and sciences and outstanding in engineering, which you should decide according to your own interests. If you are interested in all kinds of knowledge, rather than a person who values reason over literature, first recommend Zhejiang University.
The second point is geography. Shanghai and Hangzhou are both in the southeast, but there are differences between cities after all. It depends on your future development direction, whether you want to stay in the city where you study or have other directions. We should also think that the people, classmates and incomes we meet in different cities are different. In addition, the high cost of Shanghai should also be considered in combination with our own conditions.
What's more, we should also think that a good major does not mean a good employment prospect, and it does not mean that you are suitable for studying. Don't be confused by the school propaganda. You should know something about the major you are applying for. The employment of electrical information is good, so it is not a problem. The key is that you are interested.
Just some of my own ideas, cut the crap and hope to give you some hints.
Cherish the rest of high school life! Take control of your own path. Wish you success!
