The reason why the self-taught examination only has preschool education is because there are only six unified examinations for preschool education undergraduate courses. Regardless of the postgraduate entrance examination or the examination of teaching resources, there are only 6 undergraduate courses and 7 specialties in preschool education. Judging from the arrangement of the unified examination in the past two years, the subject arrangement of the pre-school education college entrance examination in April and June is different. Self-taught examination is a form of self-taught examination, which is a general term for several academic forms derived from the self-taught examination of general higher education.
