Basically, it can be a new course to start learning again. The only factor that determines whether a university can learn mathematics well is interest. Generally speaking, people who are good at math in high school will be more interested in math, so they can learn math well in college.
The mathematics courses of electrical engineering include advanced mathematics, linear algebra, analytic geometry, complex variable function, cybernetics, signals and systems, etc. Because it is divorced from practical application, the following mathematics courses will inevitably feel boring in the process of learning. If you are interested in mathematics, it will be very enlightening for you to read books such as operational research \ systematics \ when studying linear algebra.
Undergraduate students majoring in electrical engineering have very limited knowledge of mathematics after employment, and almost 90% of their jobs do not need to pay attention to these courses.
