How to lay the foundation depends on your own conditions. Since you want to call 120, I suggest you have your own review progress. First, you should have your own review outline. First, scan each chapter and section by yourself. That's enough. It's okay. Then don't say that you feel that you can do anything in the first round of review. Only when you play well in the first round can you have speed. Then you can do the first round of exercises according to the review speed.
With a foundation, we can attack big problems. Anyway, I think we must accumulate experience. Many times we will know the knowledge points in the exam. It's that deformation technique or a special way of answering questions. These experiences can be accumulated through peacetime.
Experience of speaking .....
1) class. I think class is very important. What the teacher said is not necessarily difficult, but it must be important. If you are learning new knowledge, no matter how thoroughly you preview it, I suggest you listen more. After the teacher explains it once, you will deepen your impression and consolidate your knowledge, provided that you listen carefully. If it is to explain exercises or review, I think I can skip the topics I am sure of and do something else. If the teacher solves problems in class, you should talk to him.
2) practice. Let's talk about the usual practice first. First of all, you must do it yourself. If you can't figure it out, you must consult someone. I suggest looking for someone with the same level as myself. In addition to the usual time-limited training and exams, it must be correct. You can't say that you can do every question on the test paper. So don't dwell too long if you don't know what you can't do. If you have no idea, just jump over and have a look below. Then you can calculate the questions on the draft paper. Don't crowd together. Calculate carefully. Lay a good foundation. Pay attention to the format of big questions. Also, make a bold guess and write the answer. By the way, you should form your own rhythm and feeling when you make your own papers. This can be practiced.
3) Wrong problem set. I believe many people have suggested this move. Basically, I always suggest this. First, I usually do some wrong questions. I have to write my understanding and analysis on them with pens of other colors. Next, I collected some questions. Then you can accumulate some "feelings" by reading more books yourself. It is necessary to do this because of the large amount of data and calculation of conic curve.
Tell me a shortcut to collect questions. Listen, cutting test papers is very popular in our class. Some questions are long and can be cut and pasted directly. There are also finished test papers, and the blanks left are used to make draft paper. So the recycling bins at the back of our class are full of useless test papers. Then we all collected a pile of draft paper. There is a pile on my computer desk now. And save money. No pain. )
Ps: Don't be bored. You can achieve the effect of writing a paper by calming down. And prepare enough calculation paper.
