First of all, Fudan is a school famous for its liberal arts and basic disciplines, and engineering is not strong. But Fudan microelectronics can be said to be an exception. Basically, it is the best in the country, at least the most famous among Fudan engineering majors, and its reputation at home and abroad is also great, far higher than that of electricians and optoelectronics. The disadvantage is that the competition is fierce and it is not in the school headquarters. After my sophomore year, I was in Zhangjiang Campus in Pudong District. The prospect of going abroad is not as good as that of basic subjects, but the employment prospect and work situation after going abroad are still optimistic.
The situation in the department of mathematics is unknown.
