Headset and Webcam

We recommend the use of good quality webcam and headset to avoid any audio or video difficulties while conducting classes. Although headsets are preferred, earphones are allowed as long as the audio quality is good.


Teachers are required to have a plain and neat background set-up, preferably white; however, it could also be colorful and kid-friendly for junior students. The background should not be distracting and must not show any unnecessary items. Classes should not be conducted with doors or any other access points visible in the background.


In order to conduct the classes well, the teacher must be clearly seen by students, so bright lighting is desired.


Teachers are required to conduct classes in a quiet environment. Conducting classes in public places is prohibited.
