Does the online exam have to be recorded from the whole body to the feet?

You should record your feet when you leave the country.

For the scene problem, it is recommended not to record in professional studios, and even some colleges and universities prohibit shooting in professional places such as studios. Choose a unified and concise shooting venue in the examination room, and there must be no other sundries or items that affect the visual effect in the shooting field of vision. The recording background should be distinguished from the examinee's clothing, so as to avoid the same color as the background, such as white clothes on a white background and so on.
