What is the last question of mathematics in Henan senior high school entrance examination?
Usually it is a combination of circle, quadratic function and graphic problem, not a single knowledge but a combination of multiple knowledge points. My suggestion is that you can do the review questions in chapters first, then do the comprehensive set of questions after mastering the contents of each part, and then find the relevant questions to do according to the mistakes in the set of questions. This should be the safest way. Good luck and good grades.
