Moreover, the most important thing in learning mathematics is to insist on doing problems, and to prepare a set of wrong problems and collect related problems together. Reflect and review the similarities of these questions, and then summarize the corresponding answering skills. In particular, the difficulty coefficient of mathematics is very large, which requires high comprehensive ability. This is also a must for the college entrance examination. Many candidates don't even understand the questions, let alone how to answer them.
Mathematics is also divided into several compulsory items to examine how students use what they have learned in books to do problems. Solid geometry tests students' logical thinking ability, and some topics need auxiliary lines and a lot of inspiration. Moreover, space vector is a deeper knowledge point after solid geometry, and solid geometry is not difficult to learn as long as it is learned. Moreover, the most difficult thing in the math college entrance examination is derivative, because if you can't even understand the questions, you can't start at all.
And analytic geometry is also a big difficulty. When I was in the exam, I had no idea where to apply the formula to these questions. Some college entrance examination questions are very similar to those in the book, but they have been adapted to a certain extent, which has increased the difficulty in general. It's just that these seemingly difficult topics can be mastered with more practice. Every subject is difficult for science students, but in order to get into a good school, they must redouble their efforts.
