It depends on your province. Compulsory 2 focuses on solid geometry and plane analytic geometry-straight lines and circles. In Jiangsu province, the requirement of solid geometry is very low, which belongs to one of the simplest contents of high school mathematics. It generally comes from the second biggest problem and is mainly based on basic reasoning and proof. Straight lines and circles have always been hot spots in exams. Although it is not difficult, it is often combined with conic curve, which will increase operability. If it is in other provinces, there are some places where the requirements of solid geometry are relatively high and difficult, and even the solid geometry can be placed in the penultimate question, which requires a strong sense of three-dimensionality. In most cases, lines and circles in other provinces are relatively basic, and there are fewer big problems alone.

This semester's series is more difficult. Derivatives and conic curves are much more difficult next semester.
