20 1 1 senior high school entrance examination, which is a big problem at the end of the senior high school entrance examination. Anyway, in those years, we were all quadratic functions combined with geometric figures, and the classification generally derived was moving points. The difficulty is not particularly great, but the key is that the calculation requirements may be higher.

Mathematics in the senior high school entrance examination is not very difficult. Most of the premise is to ensure the accuracy of the previous small questions and the geometric proof and simplification of the first few simple big questions, so the score is very high. Generally speaking, the last question I remember is not about difficulty, but about time. If the previous question is completed quickly and the correct rate can be guaranteed, the last question is not difficult, but it takes a long time, and most of it will involve classified discussion ~

Just focus clearly ~ I wish you success!
