I declare that my math is generally above 140, and I have never done 130 (full mark 150). Let me give you a suggestion: high school mathematics mainly needs to do problems and do them in categories. In fact, the connection between the various parts is not as great as imagined. Choose, fill in the blanks, do big questions and practice separately! The big problem is nothing more than a few big pieces. You're only a senior. You still have time. Please analyze where you will be detained every time, whether to fill in the blanks or choose big questions, and then carry out targeted training, which must be targeted, otherwise it will be difficult to improve. In this way, except for the last two questions of the last big question, you may not be able to do it (after all, this is to open the gap between us), and the highest score of the two questions is 12 to 14, which ensures that you will do every question correctly and cannot get rid of it.
