If you don't prepare for the senior high school entrance examination, but some key high schools take exams in advance, enroll students independently, and pre-record exams. You can do some Olympic math problems properly, but you should also learn basic knowledge and basic problems well. After all, at any time, the foundation is the most important. In this case, if you study Olympic Mathematics, you should try your best to integrate with the teaching materials, and you can choose to cultivate excellent ones. It is very necessary to expand and extend on this basis. You can't choose something completely different from the textbook.
I am now facing the senior high school entrance examination and passed the key high school enrollment, so I clearly understand. Those students who are top-notch in Olympic Mathematics in primary schools are not as good as me now, and I have never studied Olympic Mathematics. Even in the face of key high school enrollment, they and I finally got in. After all, the basic questions and basic extension questions in the senior high school entrance examination account for 100%, and the enrollment of key high schools is also 80%.
