As an undergraduate, what did you learn in your university?

A senior dog who has graduated from undergraduate course can just come to share his four-year experience in college. I didn't know much about any major when I volunteered for the college entrance examination, so I wanted to learn a major related to military industry. Finally, I chose communication engineering, an ordinary 211. Now it seems that the choice is good, I am more interested, I can learn technology, and I don't have to worry about employment. Our major is basically similar to that of electronic information engineering, and it belongs to the Institute of Electronics in our school. I have almost all the courses, all of which are electronic professional courses plus communication-related courses. High number in freshman year, probability theory. Linear algebra, c language, big things. Sophomore, analog electricity, digital electricity, signals, circuits, mathematical methods. In junior year, DSP, communication electronic circuit, microcomputer principle, assembly, electromagnetic field, computer network, embedded, optical fiber communication, mobile communication, communication principle, microwave, professional foreign language, single chip microcomputer, communication network, electronic measurement, etc. Our professional courses are really a little difficult at ordinary times, and there are many experimental courses. Many specialized courses have experiments, and many course designs are busy at the end of the term, even at ordinary times. Summer vacation is basically at school, preparing for the game. Electric competitions, drones and so on. At least you can learn a lot. At present, some of our majors go to graduate school, some work, and jobs are basically not worrying. Even if our grades are poor at ordinary times, those who fail to take the make-up exam have found good jobs and good salaries. The southeast coast is basically 8, ~ 1,, and the individual 1w+ is 6, ~ 7, in the mainland. Some boys get 1, in general, in our second-tier inland city. There are also many graduate students. After all, if we want to take a technical post in the future, we should need to go to graduate school to enrich ourselves. There are also undergraduate jobs with strong hands-on ability. Anyway, on the whole, it's not a loss to learn electronic communication.
