Ordinary students can only do some simple basic problems, but they can't do anything about comprehensive problems. The main reason is that you don't understand the basic knowledge thoroughly and apply what you have learned. So first of all, we should lay a good foundation, read more books and recite formulas, and do a good job in basic knowledge.
Secondly, observe carefully and think positively. Don't be a passive receiver of information, fully mobilize your enthusiasm, follow the teacher's teaching ideas, and actively think about the teacher's explanation. Conclusion It is better to learn from students' own observation, analysis and reasoning than to listen to ready-made conclusions first.
Third, master appropriate learning methods. Many students are fragmentary knowledge points in physics and mathematics, and have no unified and integrated knowledge. It is necessary to string these knowledge points together and put knowledge blocks and knowledge systems together.
In addition, physics and mathematics need to do more problems. On the basis of doing problems, we can deepen our understanding of knowledge and familiarity with questions. Only by doing more problems can we improve. Math, methods are very important. To sum up your own answer methods, you can buy a tutorial book that explains this method more. Doing math problems is the most taboo. If you look at it, you will make a mistake. So do more questions, don't be eager for quick success in the exam, make sure you are doing the right thing. Physical chemistry and biology, the most important thing is to remember the formulas in the book, find a tutorial book with detailed answers, and do more exercises to practice your hands.
There are many knowledge points of mathematics and physics in junior high school, so students may not be able to adapt at once. I met a child in Meng Ping, who was also poor in physics and mathematics in junior high school and had a good foundation, but he just couldn't do problems, and his grades improved rapidly under the guidance of his teacher. The key to your study now is to master the basic knowledge, organize and integrate what you have learned, do more exercises, and ask teachers or classmates for help if you have difficulties in learning. Of course, it's not bad to find a tutor. I hope it helps you!
