Candidates who sign up for preschool education can also fill in the pairs of preschool education voluntary schools. Candidates who register for pre-school education can fill in the pre-school education voluntary school. When enrolling students in colleges and universities to fill in their volunteers, candidates can choose relevant schools of their major and fill in relevant information in the volunteer filling form. For candidates majoring in preschool education, it is a more appropriate choice to fill in the voluntary school for preschool education, which can better adapt to their professional background and hobbies and improve the probability of success in applying for the exam.
