List the outline of knowledge first and focus on your own weaknesses. Then do a good job according to your actual situation. The questions you have done should be carefully revised. It is best to write down the problem-solving ideas, error-prone points and knowledge points beside them. Only by mastering a class of problems through one question can we really learn thoroughly. There are not many questions, but they are comprehensive. Introspection and summarization are always more effective than just doing problems. It is suggested that you can do a little problem every day and make progress every day. Come on, I wish you academic progress!
