According to the principle, mechanical specialty is engineering, which requires higher mathematics and physics.

But the mathematics in our high school is very different from that in the university.

The connection is not very tight

My personal feeling is that high school mathematics can't be very good. It is best that you have good spatial thinking ability, because it is needed in mechanical drawing. You can construct a three-dimensional drawing in your mind based on a two-dimensional drawing.

Of course, there are advanced mathematics, probability theory, mathematical and physical equations and other courses. In college. If you hate math very much and have no confidence in it, you should think carefully, and some may fail.
