I am a junior, majoring in communication engineering. I plan to take the postgraduate entrance examination and cross the direction of financial investment. Besides a few preliminary courses, what else do you need to prepare at ordinary times? Now many college students want to take the road of financial investment. I suggest you start with textbooks and go out to find a type of enterprise while studying. To put it bluntly, this major is a one-stop major. Three years for entry, five years for entry and ten years for entry. In practice, it is more expensive than persistence. Good luck!
