Because math scores are improved quickly, in fact, as long as the knowledge points and formulas are memorized, and at the same time (this is also very important), it is necessary to practice doing problems. Otherwise, if you don't memorize the formula well, you will forget it and understand it incompletely. Because the math score is very high, if the basic knowledge is weak and the multiple-choice questions are not answered correctly, it is basically 40 to 50 points. At this time, it is easy for students with good foundation to get 90 points, not to mention good math. It is easy to get 80 to 90 points at once.
