Mathematics in Zhejiang college entrance examination generally pays attention to avoiding university knowledge, at least it won't let you solve problems directly with university theorem. However, if you look at the math college entrance examination questions a few years ago, there are still some questions with high numbers. For example, the derivative problem of a certain year (I forget the specific year) can be solved by Robida's law, but this is only one step of this problem. This step can be solved by conventional methods (that is, the process). Many problems are the same, and using college mathematics is only one method, not the only one. Then, there are some finale questions to fill in the blanks. Most of these topics are based on new concepts, telling you some simple advanced mathematics knowledge and testing your learning ability on the spot (my math teacher calls this kind of topic the simplest one). This kind of topic can be given at will, so there is no need to learn advanced mathematics for this kind of topic. For mathematics, my advice is that you should try not to learn advanced mathematics in high school, which is not worth the loss (I am a lesson from the past). Of course, if you have the spare capacity to study, you can learn some simple and quick things, such as Robida's Law, Cauchy Inequality (solving some final questions that choose to fill in the blanks), determinant (quickly calculating normal vector), Taylor formula (remembering the first three digits is enough, and scaling series is useful). These should be enough, greed is not worth it, but essence is more important.
