If the time to enter the waiting room is from 15: 45 to 16: 00, it is recommended to arrive at the examination room about half an hour in advance, that is, from 15: 15: 30.
Before entering the examination room, you need to go through a series of processes such as arriving in the waiting room, starting to draw lots, and entering the examination room. Therefore, in order to ensure that there is enough time to enter the examination room, it is recommended to arrive at the examination center in advance and wait outside the examination center, and then enter the waiting room after the exams are over.
