Scope of mathematical investigation: The mathematical problems in key middle schools are still dominated by Olympic math problems, with a small number of primary school mathematical problems, and some schools investigate a small number of junior high school mathematical knowledge.
Difficulty of investigation: from the previous years, the difficulty is slightly lower than that of cup and joint exam; However, many key senior high school entrance examination proposition teachers change every year (because the first-grade teachers rotate every year), and the proposition often does not have a continuous style.
The distribution of grading examination results is roughly as follows: primary school classroom knowledge accounts for 20%, primary school olympiad accounts for 75%, among which some simple junior high school knowledge is obtained, accounting for only 5%, and junior high school grading examination language is generally three blocks: basic words, reading and writing. Last year, a school directly asked students to write only one composition.
