Imagine that the online examination system of Baiyi can capture the invigilation process with a real-time camera. During the examination, the system will ask candidates to turn on the camera and capture the candidates' status regularly according to the time interval set by the administrator.

Imagine that the online exam of Baiyi is still quite strict. Imagine that once the online exam begins, you can't quit the exam process halfway. If the user quits the online exam, the exam will be invalid.

Imagine Baiyi app, a software for learning and education, a huge amount of learning content, and different curriculum arrangements. We can search related knowledge points and databases according to our own study plan, and recommend learning modes from multiple angles, which can effectively help us master different knowledge points, learn through entertaining, relieve tension and learn in the process of mutual communication.
