When the entrance of the test center is opened, enter the entrance of the test center with the admission ticket.
After entering the examination center, look for the distribution map of the examination room (including the waiting area and the examination room) and the location of the bathroom in the examination room to prepare for your own exam.
Prepare to enter the waiting area. Before entering the waiting area, the staff of the examination room will issue 32K envelope paper bags for candidates to put their mobile phones, write their names and admission tickets on the envelopes, and then put them in the boxes prepared by the staff to remind everyone to remember their box numbers in case they can't find their belongings after the exam.
Enter the waiting area after handing in the mobile device, and you need to queue up to enter. You must see your waiting area clearly. Why? Because you have to draw lots in the waiting area to decide your exam order.
