Classmate, maybe you are not confident. When I first entered high school, I scored more than 50 points, a little better than you. But I never gave up math. As long as you put your heart into it, you've always been seventy or eighty years old, and you've never been. You broke through the post-90 s in your sophomore year, but you still often fail. If you do hard in the exam, you will still get 50 or 60. Until the first round of review in senior three, I was also poor. I remember that I got more than 60 points in a bottom-up exam and was ashamed to go home to see my parents. I still make a fuss about mathematics. If I don't understand anything, I insist on asking questions and doing problems. Finally, in the third year of high school, mathematics reached the top five in the class next semester, and it was the first in the class several times. Although I didn't do well in the college entrance examination, I did 108. . .
