Primary school mathematics teacher recruitment examination, professional knowledge is to test high school mathematics or college mathematics, or Olympic mathematics knowledge? If you have any teaching materials, please recommend them. I have worked in a primary school for many years, and I have experienced the primary school teacher recruitment examination and the primary school teacher professional knowledge examination. General professional knowledge examination, because I want to engage in primary education, so I don't take it. But you must have the ability to analyze and grasp the teaching materials. As for the primary school olympiad, you must take the test to see if you have the ability higher than the textbook requirements. There are problems in middle school, but not too many. Most of them are elementary school knowledge, and there is definitely no problem in college. Because you are a primary school teacher, you don't need it.
