Candidates are free to bring materials and textbooks to take the exam, but they are not allowed to discuss answers with each other or borrow other people's materials. Compared with the closed-book exam, the open-book exam is more open and flexible.

Because in the open-book exam, candidates can read textbooks, so the questions in the open-book exam are generally original questions of the proposition group, and the proposition materials and questions will not be selected from any counseling materials and any version of the textbook.
