We should arrange a simple and feasible plan to improve our learning methods. At the same time, we should properly participate in school activities and develop in an all-round way. In the process of learning, we must: listen more (attend lectures), remember more important topic structures, remember more concepts and formulas), read more (read books), do more (do homework), ask more questions (ask if you don't understand) and do more experiments. Summarize more. Concentrate by taking class notes. Basic essentials of chemistry: skilled memory+practical operation, that is, chemistry is a subject based on experiments. Learning should combine skilled memory with practical operation. Especially, it is easier to remember the concepts of periodic table of elements, priority of metal reactions, chemical reaction conditions, precipitation or gas conditions. That is, you have to memorize the first 18 elements of the periodic table. We should give priority to understanding and mastering the chemical properties of chemicals, especially familiar with chemical equations and ionic equation's writing. We should master the use of chemical experimental instruments and the basic operation of chemical experiments, and design some typical experiments. Physics: The key is to be able to apply independently and master physical ideas. Try to draw pictures when doing problems, and change abstract thinking into image thinking. The definition of theorem must be mastered, and several plates must be learned: energy conservation, momentum law, mechanical energy conservation and kinetic energy law in mechanics; Lorentz force, left-handed rule and right-handed rule in electromagnetism. We must firmly grasp the definition of the theorems involved. Pay attention to the teacher's problem-solving ideas when encountering problems. First of all, it refers to solving the problem with the knowledge of office, heat, light, electricity and atomic physics, and then digging out the known conditions, especially the implied conditions. No matter how difficult the topic is, try to draw pictures, turn abstract thinking into image thinking for state analysis and dynamic analysis, and then build a bridge between the known and the unknown according to what you have learned, and apply it independently to cultivate your body and mind. Through unremitting efforts, the results will be improved and stabilized step by step. Try to prepare for the exam, be careful when taking the exam, and be calm when sprinting at last. After the exam, you should sum up carefully so that you can study better in the future. Now: let go of the burden and study hard at ordinary times. Before the exam: prepare carefully, during the exam: never give up, after the exam: calm down. Remember! Success always comes from unremitting efforts, and success always belongs to diligent people. I wish you success!
