CBT Exam Browser – Secure Browser for CBT Exams
CBT Exam Browser is a specialized web browser application for Computer-Based Testing (CBT), designed to help students take exams safely, stay focused, and avoid distractions. The app uses screen lock mode and multiple security protections to prevent participants from switching apps, taking screenshots, recording screens, or copying exam content.
The application supports both local (LAN) and online exam servers, making it suitable for schools, universities, training centers, and computer-based assessments.
