Do you need to seal the examination room for a week for CET-4 and CET-6?

The examination rooms of CET-4 and CET-6 don't need to be closed for a week, but only need to be arranged one afternoon in advance. The CET-4 and CET-6 only takes two days. The first day is CET-4 and CET-6, and the second day is usually Saturday and Sunday. In other words, the staff or students will arrange the examination room on Friday, but there will still be classes on Friday. Because college courses are not very tense, there is generally no evening self-study on Friday. The examination room will be arranged on Friday afternoon, and then it will be closed after the exam, so it is actually equivalent to the exam that was closed the day before the exam. Students take CET-4 and CET-6 in our school, and they don't have to be sealed for a week.
