Overview

The PC&B experimental operation examination and teaching training system delivers full-process digital examination management β€” "on-site exam, real-time assessment" and "complete exams before unified scoring". Question drawing, video recording, marking and appeal evidence collection are fully digitized.

Fairness is engineered in: random question drawing prevents leaks, multi-camera recording preserves evidence throughout, and AI-assisted scoring supports objective marking. One integrated deployment simultaneously serves three scenarios β€” examination, teaching and training β€” maximizing the value of every lab.
