The content range of written mathematics test in primary school and junior high school of special post teachers in Yunnan Province is different. Because Yunnan Tegang teacher's knowledge of primary school mathematics is different from that of junior high school mathematics, the primary school is a little simpler, the junior high school is a little more complicated, and the examination subjects of primary school and junior high school are different, so they are tested according to different subjects. Therefore, the content range of mathematics written test in Yunnan special post teachers' primary school and junior high school is different.
