Physics is difficult because the publicity of physics is abstract, but the topic is flexible. Often a knowledge point can lead to many problems, and a topic can also involve multiple knowledge points. Physics also needs mathematics as a tool to solve problems. Biology needs to remember, which is not flexible, chemistry needs to remember equations, and the topic is not flexible, so it will always be those points. If you are good at chemical biology, you should actually study pharmaceutical engineering, chemical engineering and bioengineering.
Math is difficult. Mathematics is a tool subject. As long as you do science, you can't do without mathematical modeling and analysis of objects. Therefore, people understand the basic disciplines of this world, which includes many disciplines. It is difficult for us to simply say that physics is difficult or mathematics is difficult. Mathematics, you don't have a solid knowledge of mathematics, it is difficult for you to make scientific analysis and calculation of other disciplines to verify your theory, so mathematics is more difficult.
The way to learn science well is 1. Learn to summarize what the teacher says in each class. If you plan to summarize what the teacher said, you will concentrate on what the teacher said in class. There may be many experiments in science, and you will be willing to participate. In the process of summing up, you should also ask the teacher for advice when you encounter problems.
2, doing the problem is essential. Doing the problem can test whether you understand it in class, which places are not firmly grasped and which places need to be improved, which can be detected in doing the problem. Science scores need to be improved step by step. No one can improve science scores a lot at once, and they all learn from the basics.
The above are some of my thoughts on math and physics study, and I hope it will help you.
