Focus on the basics
Learning math is the same as building a house. The most important thing is to lay a good foundation. Without a solid foundation, how can we continue to build? So when learning mathematics, don't simply ignore some basic knowledge, let alone overestimate yourself and directly challenge the most difficult ones. Step by step, never reach heaven in one step.
-Listen carefully and review and consolidate.
Students must concentrate on listening, watching, feeling, speaking and touching in class. Many times, what the teacher says in class happens to be the most important, so don't ignore what the teacher says in class, and be sure to take notes (as detailed as possible, indicating key points, difficulties and details).
Guide children to improve their self-adjustment ability of "teaching suitability"
Generally speaking, after a period of teaching practice, due to different understanding of the teaching process, knowledge structure, thinking characteristics, personality tendency, professional experience and other reasons, teachers show a certain tendency in the adoption of teaching methods, means and strategies, forming their own unique and consistent teaching style or characteristics. As a student, it is obviously unrealistic for teachers to adapt themselves. We should optimize our learning strategies, standardize our learning behaviors and gradually adapt our learning methods to teachers' teaching methods according to teachers' characteristics and our own reality, so that we can learn well and quickly.
Do more exercises and summarize.
Many students will say, "I have done a lot of questions, why can't I do them in the exam?" . First of all, do you do the exercises by yourself? Have you summed up the solution to the same problem? Can you infer from one example to another? Doing exercises is not to complete the task, but to test whether you have learned and understood. It is also a review and consolidation of what you have learned. The problem is not to do more, but to do well. Learn to learn from experience and lessons, sum up methods, so that the questions are effective.
