If you want to engage in professional-related work after graduation, you must master basic things such as analog electricity, digital electricity, single chip microcomputer, and some related software, such as PROTEL, keil, proteus and so on. . . Anyway, it is a series of schematic diagrams, PCB and simulation software. After coming out, there are many kinds of software used by the company, which requires a certain degree of understanding, but we must master one (one for each). Programming must learn C and assembly well, so can C++. . Wait, wait, wait, wait, wait, wait, wait, wait, wait.
I haven't taken a double degree or anything, but I can still try if I have time, thanks to you. But originally our major was related to computer and communication, so I don't think it is necessary to learn computer (anyway, this is the case in our school, and many computer courses are the same as ours, but the focus is different).
Certificate, CET-4 and CET-6 are necessary, and computers are all floating clouds, but speaking is better than nothing. You can take other certificates when you are free. Anyway, if you have more, you won't suffer. Especially English, you don't need a certificate. You must be able to read, read and understand yourself. . . . Let's just say.
I suggest you run down from the lab at school and do some projects with the teacher, which will be very helpful to you and will be much easier after you come out (I will suffer this loss. . . . . )
That's all for now. Four years in college is really short.
