Online proctoring will be split into Zoom/Google Meet etc. and screen recording.
Zoom/Google Meet
During the contest, have a device (such as your phone, a second laptop etc.) watch you from the side.
It should capture your screen, your face, your hands, as well as your desk.
Here is an example screenshot:
Screen Recording
You should have a screen recording of the entire contest.
The default applications (e.g. Snipping Tool on Windows) usually take up too much space, up to or larger than 10GB. Thus, the recommended way to record the screen is given below, which is tested and the resulting file will be around 300MB for 5 hours of recording.
Refer to the screen recording guide.
