My experience: 1, establish the idea of doing more problems and practicing basic skills hard, and don't be opportunistic; 2. Find out your own weak links and make a plan to overcome them. The methods are as follows: 3. Focus on the weak links and make efforts and time to overcome them. The specific method is to thoroughly understand and digest the textbook knowledge of this link, including examples and exercises after class. Don't do difficult, off-topic or strange questions, or you will lose confidence in the process. This is the foundation, it shouldn't be difficult. The key is to do it with your heart and don't look down on others. 4. After understanding the textbook knowledge, find exercises to do. Note: each question and each question bank only choose the questions related to this link to do, and do nothing else, and it must be easy before difficult. This link is the most difficult. When you master this link to a certain extent, you will be delighted to find that most of the questions are very simple. At this time, you don't have to do everything, just look at the problem, understand the problem, and run through the ideas for solving the problem in your mind, which will save time. If this effect can be achieved, then this link will be passed. 6. Solve the next weak link in the same way. 7. The purpose of this is to break the weak links through special targeted training. By doing a lot of questions, you can make sure that the exam questions are the original questions you have seen or even done, so the exam is simple! I hope it helps you.
