What is the difference between science calligraphy and college entrance examination science?

The content of high school study is completely different. I think the biggest difference is that the choice of liberal arts is very narrow when the college entrance examination is completed. Many majors do not recruit liberal arts students, and the scores of liberal arts in schools are relatively high. Especially good universities, some seemingly liberal arts, such as land and resources, only recruit science students. Of course, there are many majors that don't accept science students, such as literature.
