Mathematics mentality collapsed.
In my experience, it is not recommended to do real questions at the end of the sprint. As you said, you will feel scared when you encounter a problem that you can't solve. You can find some corresponding questions, do some classic examples, see the solution ideas of the examples, and then prescribe the right medicine, the effect will be much better.

Because I'm not from Shanghai, I searched Baidu Library for 24 questions and 25 questions you mentioned, and found that they are all classic analytic geometry. For this kind of questions, the geometric relationship in the figure is the fundamental starting point, and the parallel, vertical and specific angles involved in the questions are the starting point. By applying various theorems, the coordinates of points can be derived from the known ones, and then the analytical formula can be obtained. The general idea is this. You need to analyze specific problems, connect various geometric relationships and find an analytical formula. I hope it will help you and be adopted.
