This is my first test of teaching resources this year. I took an examination of high school mathematics teaching resources, which is the first time to take an examination of high school mathematics. I reviewed for about five days, so I bought review materials and read the knowledge points in the book first. First of all, I want to go through the knowledge of mathematical analysis, advanced algebra, analytic geometry, probability theory and mathematical statistics, and remember the commonly used theorems and formulas, and then each chapter has supporting exercises. I have to do exercises. The part of subsidizing high school mathematics is about mathematical analysis, advanced algebra, analytic geometry, probability theory and mathematical statistics, which is difficult to test this year. After the exam, many people say that they didn't do well in the exam, but I think this year's funded high school mathematics is not very difficult, but it is actually partial to the foundation, so we must lay a good foundation.
