There is a high probability that the result will be invalid.

Enter the examination room, find your seat quickly, don’t make any noise, and keep quiet. Quickly fill in the question form prepared by the teacher. The form will be divided into upper and lower parts. You need to write your name and registration number in both parts. After the experiment is completed, the teacher will grade it, and you will need to sign again to confirm the grade. If there is no signature to confirm the score, the score will be invalid.

When doing experiments, if there is an instrument failure, don’t panic. You can ask the teacher for help. No points will be deducted for this. If you really can’t do it, you can ask the teacher to guide you through it. Generally, teachers will deduct one or two points for this operation step, which may differ according to the requirements of each region.
