Assistance
If contestants wish to go to the toilet during the test, they must make a request using the Questions / Announcements feature. Contestants may only go to the toilet upon approval by the invigilators. The invigilators may reject any request that is deemed excessive, or if another contestant is visiting the toilet. It will be regarded as cheating if you leave the seat without the invigilator’s approval.
