Poor math is good, poor math is not good. After all, our machinery needs a lot of physical knowledge to support, as well as calculation and verification. In addition, generally speaking, mathematics is gradual, so we should learn it slowly. When your mechanical theory requires it, you will study mathematics, instead of not studying mathematics after learning machinery. Nothing, as long as you have studied physics and mathematics, you can learn mechanics. As for what height you can reach, you have to rely on your own efforts! Come on, kid!
