This classmate, as an experienced person, I'll tell you some methods: First, when you take the exam, read the whole volume first, and don't panic when you see that you can't do it. You should strengthen your confidence, it is difficult to trust others. When doing the problem, I tell you a very important point, which may affect your life: be sure to use the draft well. When the draft is handed out, divide it into several pieces, fold it up, use a pen, or something else. When doing the problem, when using the draft, you should mark the draft with the title number, isn't it a block? Ask one question at a time. In this way, when you check, you will know where you are wrong, and it will be clear at a glance, so you don't need to recalculate again, saving time.
Besides geometry, it can be said that it is a score-preserving problem, and you must get full marks. When you come across a geometry problem, you will never leave it. Personally, I suggest preparing a wrong book. You can sort out the wrong questions separately, for example, this is analytic geometry and this is solid geometry. Be sure to prepare a wrong book and read it before the exam or when you are free.
There are only two methods of solid geometry: coordinate method and geometric method. If you can't meet them, your thinking is not very clear. The coordinate method is suggested. Although it is complicated, it will definitely score. Again, the book prepared is wrong. Finally, mentality is also very important. Keep a good attitude and take your time.
I believe you can do it. These are my real thoughts and opinions, hoping to help you. I hope to adopt. Thank you.
