First of all, don't worry about interdisciplinary issues. Cross-discipline, especially pedagogy, has become commonplace. In colleges and universities, because of the limitation of mathematics, I believe many students have crossed the border into pedagogy.

Secondly, regarding the difficulty, the number of participants in the postgraduate entrance examination for pedagogy is indeed rising. At present, pedagogy, economics, management, literature, law and engineering are all subjects pursued by students, and they can definitely be said to be hot subjects. Compared with science, agriculture and philosophy, the difficulty is definitely great, so it is better to take the postgraduate entrance examination in junior year, because in the future, the number will be more and more; And now the opponents facing the postgraduate entrance examination are no longer simple students who should be bound. There are many students from World War II and even candidates from World War III.
