Yes, pre-school undergraduate education can be interdisciplinary. According to the provisions of the Examination Center of the Ministry of Education, pre-school undergraduate students can take cross-disciplinary examinations and graduate studies, and can obtain master's degrees in pedagogy, psychology, sociology, politics, economics, law, literature, history, science, engineering, agriculture, medicine, management and other disciplines. First of all, students need to check their own school's postgraduate entrance examination policy, understand the requirements of interdisciplinary examination and research, and the relevant processes of postgraduate entrance examination. Secondly, students need to determine the professional direction of postgraduate entrance examination according to their professional background and hobbies, and be familiar with the basic knowledge of postgraduate entrance examination. Finally, students need to make a perfect review plan and review in an orderly way according to the plan in order to achieve good results in the postgraduate entrance examination. My tip is: before the postgraduate entrance examination, students should take more remedial classes for postgraduate entrance examination, so as to better master the postgraduate entrance examination knowledge and improve the postgraduate entrance examination results.
