I don't want to throw cold water on it. My math score is almost the same as yours, and the college entrance examination was held back by math. Personally, I think I put mathematics in a very important position when I was preparing for the third year of high school. I brush the questions every day, but in the end, the college entrance examination didn't improve. Maybe I didn't find the direction. You can find a better math and ask how to learn it. I don't think learning should be hard work, and skills are also very important. In the past 20 days, I believe.
