You should know that the prospect of IT industry is very bright. If you want to learn computer well, you should focus on innovation and practice!
Math just exercises your logical ability and way of thinking. On the surface, it is useless to be good at math. You must know how to use the thinking mode in mathematics to innovate and develop in the field of software engineering or communication engineering. Some people are good at math, but they still can't learn computer major well. It is precisely because of the above reasons that employment is difficult.
Of course, since you have chosen the computer major, you should study hard at math, and more importantly, you should be able to read English, because all good computer books are published abroad. Reading original English books is absolutely impossible without a good English level! !
I sincerely hope I can help you! ! !
