1 All adult undergraduate and second-degree students can't get the mechanical undergraduate diploma, because this major is so strong that you can only get the applied degree after systematic study. If you want to get a degree, you can take the postgraduate entrance examination. According to the current national policy, you can get a master's degree after working for three years after graduation.
If you want to do mechanical work, you don't need to be good at math, because many things are dead, and you can learn by doing more and learning more. However, you don't need to be too good, not that you are particularly bad. At least the most basic trigonometric functions, calculus and differential equations should be solved, and at least you can understand mechanical formulas, because the design is mainly based on mechanical formulas, so you can know whether your things can pass the test in theory through design and verification.
If you just want to do mechanical work, the quickest way is to go to a technical school. Don't laugh at this man's low academic qualifications, but he has a strong practical ability. Although he is a worker, he is very tired. Generally, CNC machine tools work in three shifts, but the worker's salary is not low, and then he can learn from experience after working for a long time before forming.
Without a bachelor's degree, it is difficult for you to find a job in mold design, because even undergraduates have to go through two or three years of post-employment training before they can independently complete the design of individual parts. Want to complete a whole mold, without a few years of work experience is impossible.
In fact, education is just a stepping stone. After entering the mechanical industry, you will be more neglected, because you can get assistant engineers, then engineers, and you can get registered engineers. Congratulations on your hard work. With this certificate, you can live a good life anywhere.
The above is my opinion on your problem, and I hope it will help you.
