Not expensive. One-to-one curriculum in primary schools refers to explaining knowledge to children through the teaching mode of 1 to 1, which can improve students' learning efficiency to a greater extent, and can also explain problems to students in time. This explanation mode is more efficient, with a class lasting about two hours, while ordinary primary school courses are charged according to class hours, with an hour of about 60-200 yuan. Therefore, it is normal to charge 60 yuan. Personally, as long as it can improve children's grades, it is not expensive to invest too much.
