University Exam update_version от shan

University Exam Lockdown is a browser security tool designed for computer lab administrators to enforce academic integrity during online MCQ exams.

Features:
- Restricts students to a single approved exam URL
- Blocks all new tabs, popups, and window switching
- Disables keyboard shortcuts (Ctrl+T, Ctrl+W, Alt+Tab, F12, etc.)
- Password-protected admin panel to start/stop lockdown
- Violation logging to track suspicious activity
- Lockdown persists even if the student tries to close or reload

How it works:
The admin activates lockdown mode before the exam begins. Students are then locked to the configured exam website and cannot navigate away. Only the admin can disable lockdown using a secure password.

Intended for university and school computer labs running supervised online exams.
