Mathematics is very difficult for junior high school. Because there are 20% math questions in the senior high school entrance examination, especially the last two questions are very difficult to write, and the final question is for the champion. Junior high school physics is the simplest basic knowledge. For example, optics only talks about the original topic without calculation, while mechanics only talks about the principles of pressure, buoyancy, work, power and lever. The mathematics knowledge used is elementary school knowledge, and the scientific counting method is the most used in grade one.

However, high school physics is very difficult. Because many problems in high school are deepened on the basis of basic knowledge in junior high school, it is not difficult to even do calculus in high school, so it is very simple to choose inequalities to do problems. Physics in senior high school is much more difficult than that in junior high school. For example, high school mechanics involves orthogonal decomposition of force, parallelogram rule, plane geometry and trigonometric function. The centrifugal movement in high school and Cape Town principle are no less than those in junior high school. Even the phenomenon of light, there are many complicated calculation problems and formulas in high school, as well as the formulas of reflection and refraction.
