Your desk demostration is a standard procedure of confirmation by your proctor that there are no forbidden equipments on your desk. This procedure is important for your exam organizer or educational organization in terms of your exam results confirmation.
We recommend you to free up your desk before proceeding to your exam:
While your desk demonstration, take your webcam or your laptop and direct its shooting objective onto your desk. Demonstrate your desk from different sides so that your proctor can see that there are no hidden and/or forbidden equipments put on your desk.
It is very important to show your desk beforehand your exam as it can affect the final status of your work.
