I didn't understand the importance of mathematics until my second year of high school, because I was the worst in mathematics in my first year of high school. But now that I'm in senior three, time is a little tight, but it's ok as long as I spend time. Don't do it blindly. The key now is to grasp the teacher's review progress, and then do the questions, preferably practicing the real questions over the years! I'm sure it will work! I got the highest math score in the third year of the college entrance examination, O(∩_∩)O~ 134! Come on, you can do it too!
