Let me ask you what to study first. If you want to do technology in the future, BMW is not suitable. Almost all BMW undergraduates have to work shifts. Secondly, BMW's job is a radish and a pit. Although BMW won't fire its employees, you won't get any appreciation at all at BMW. Those who retaliate will take the initiative to leave. This is a waste of youth and the best time to learn skills there. What is good about BMW is its treatment and sense of belonging to its employees. I graduated from 12 and worked in BMW for 8 months. I resigned voluntarily. Although my salary now is much worse than when I was at BMW, I have learned something now. Maybe in a few years, my skills will be more skilled and there will be better room for development, instead of waiting for work at BMW. You are in/kloc-class 0/4,/kloc-class 0/2, class 65438.

Some conventional math problems, Chinese problems, some analysis problems, and some professional knowledge of numerical control technology.
