Is it necessary to buy 53 for special post mathematics?

Mathematics learning and teaching need to simulate the five-year college entrance examination for three years, which is a good counseling material. Special post teachers are a special policy implemented by the central government for rural compulsory education in the central and western regions. By openly recruiting college graduates to teach in rural schools below the "two basics" counties in the central and western regions, we will guide and encourage college graduates to engage in rural compulsory education and innovate the supplementary mechanism for teachers in rural schools.
