A batch of undergraduate students, also known as "emphasizing the original" or "one book", refers to the first batch of schools enrolling students at the undergraduate education level during the college entrance examination in Chinese mainland, and the score line should generally reach the admission line of a batch of undergraduate students. The second batch of undergraduate students (also known as the second batch of undergraduate students) refers to the schools that recruit undergraduate students when enrolling students in the college entrance examination in China, and the admission scores should generally reach two lines.

The difference between one book and two books.

1. Admission batches are different: one is the first batch and two are the second batch.

2. The tuition fees charged are different: one or two books are relatively few, but some transfer to two books is relatively high.

3. One is in the "public class"; Most of these two books belong to the "public category", but very few also belong to the "private category".
