I'm embarrassed to tell you about my study experience here, so let's throw a brick to attract jade. I hope all the students and teachers can give us valuable suggestions. The following are some of my experiences for your reference only. I will sincerely accept your opinions and suggestions. In life, if you don't trim the wood, you won't be able to make it, and if you don't teach it, you won't be able to make it.

The key to learning mathematics lies in concentration and meticulousness. Every student like me can do it. Why would I do that? Because I do it very carefully. I'll check it again after I finish it. As long as I make the concept clear and check it out, the math problem will naturally not go wrong.
