The knowledge in high school is different from that in junior high school, not only because you have the right attitude, but also because you can get it through hard work. Many students in our class study hard, but they are not very good at math and physics. Mathematical physics requires a high way of thinking, so it has strict requirements on learning methods. According to my study experience, mathematical physics, especially physics, should not be overemphasized on practice. Mathematics needs a solid foundation and more practice. But more importantly, we should think carefully about every problem we do and don't always want to do new ones. In-depth thinking and method summary of old problems will be of great help to learning. There is also to consolidate the basic concepts, be familiar with all the concepts, and read the concepts thoroughly with the help of topics and turn them into your own things. Doing problems with blind concepts will only get more and more confused. In addition, high school mathematics and physics are modular, and knowledge is interrelated. Comparing similar knowledge together will make learning much easier. In addition, I suggest you encourage your children more. In the second year of high school, there will naturally be a sense of tension when you really want to learn well. It's normal to be stressed, but stress is not something that hinders people's progress. I have always believed that strength supports self-confidence. When your child has enough strength, pressure will naturally turn into motivation, so your encouragement will be of great help to your child. In addition, don't interfere with your child's study too much, which will make your child dislike you. And encourage him to exercise more, don't shut himself up at home and study hard, certainly not. Only when he is in good health can he put more energy into his study. Finally, advise your children not to be confined to textbooks. Knowing some application fields and advanced knowledge similar to what you have learned will bring some help to your thinking and learning.
