The senior high school entrance examination is a comprehensive survey of the learning content of the whole primary school, so all the knowledge from/kloc-0 to grade 6 will be tested. In fact, there is little new knowledge in school in the sixth grade, and the subsequent stage is to comprehensively review the knowledge of primary school for six years, so the final junior high school entrance examination will include all these contents.

However, due to the limitations of the types of questions, the amount of questions, and the time, the exam will be focused. Solving problems involves some knowledge, such as the related operation of integers. This knowledge point may not be specially investigated when calculating problems, but it will actually be involved when doing application problems.
