This year is the first exam after the reform of the new senior high school entrance examination in Tianjin. The biggest change is that history, morality and legal system are included in the total score of the senior high school entrance examination, and it is an open-book examination. Today, parents of some schools have received the notice from the class teacher, explaining in detail the prescribed books for these two open-book subjects. Tianjin Admissions Office has chosen a relatively compromise way: only textbooks can be brought into the examination room, and no materials can be attached to the textbooks.
