In the math exam, I often can't do the finale, but I can often do it after my classmates are sarcastic (joking). Why?
Although it's a joke, it still touches your little sense of inferiority and gives you motivation to learn to do math. This is also as the saying goes, be brave after shame. Of course, it is also possible that classmates' jokes inspired you to learn mathematics and improved your interest in learning mathematics problems.
