First of all, we need to understand the function of the wrong question book before establishing it. Broadly speaking, it is an important means to improve learning efficiency, improve learning quality, consolidate learning foundation and create excellent results. However, many students didn't notice. In fact, the wrong questions they misunderstood are not necessarily just wrong questions, but should include wrong questions, easy-to-mistake questions, difficult problems, typical questions and so on. It should be the combing of knowledge, the collection of key points, especially the refining of important and difficult points. Based on the key analysis of systematic learning, let a student who is affiliated to the National People's Congress and has been studying well tell the author that "wrong topic book" is indeed an effective learning method: 1, and "wrong topic book" is a systematic summary of his mistakes. Summing up the mistakes together, it is easy to see the regularity. 2. The "wrong question book" can change students' attitude towards mistakes, which is the key to reduce them. Mistakes are precious, because mistakes can make students realize their own shortcomings, and they can't be ignored because there are few wrong questions or simple reasons. A mistake is actually a blind spot. If you don't take a positive attitude towards mistakes, or lack an ideal way to solve them, mistakes will happen at any time, and often happen repeatedly. We must treat mistakes "kindly" and "strictly". 3. "wrong title book" can get rid of the bad habit of being so-so. Students do their homework carefully because they are afraid of copying wrong questions or too many wrong questions.
