I found that every time I took the math exam, I did the difficult and complicated questions very seriously, but I didn't want to listen to the teacher's comments after I found the mistakes. What should I do? Do you feel that you have worked hard but got nothing?

In fact, the so-called difficult problems and complicated questions are not written by many people, but you can write them (although it is wrong), which proves that you are still full of confidence, but you overestimate yourself. The teacher doesn't want to listen when he is talking. You might as well try to show it to the right students before the teacher comments. You can see them or ask them. By comparison, you will find something (I don't need to say anything). )
