When you start a test, PrepMocker automatically activates exam mode — just like a real exam centre.
Here is everything that gets enforced the moment your test begins:
🖥️
Fullscreen Mode
The page enters fullscreen automatically when the test starts. Exiting fullscreen triggers a warning and forces you back in.

Switching to another tab is detected instantly. After 3 tab switches, the test is submitted automatically.

Live Countdown Timer
A real-time countdown is displayed in the header. When time reaches zero, the test auto-submits — no extensions.
💾
Autosave Every Answer
Every answer is instantly saved to the database. Even if you refresh the page, no response is lost.
🖱️
Right Click Disabled
Right click and the browser context menu are completely disabled throughout the exam.
📋
Copy / Paste Block
Text selection, copy, cut, and paste are all disabled. Question content cannot leave the exam window.
⌨️
Keyboard Shortcuts Block
F12, Ctrl+U, Ctrl+S, Ctrl+C, Ctrl+P and all developer tool shortcuts are blocked during the exam.
🔍
DevTools Detection
If browser developer tools are opened, the system detects it immediately and clears the console.
🖼️
Image Save Block
Question images cannot be downloaded, saved, or dragged out of the exam window.
📱
Question Palette
A color-coded grid shows the status of every question — answered, skipped, marked for review, or not visited.
🎯
SC / MSQ / NAT Support
Single correct, multiple correct, and integer type questions — all three NTA question types are fully supported.
📐
MathJax Rendering
All Physics and Mathematics equations render perfectly using MathJax — exactly as they appear in textbooks and NTA papers.

Important: Tab switching, fullscreen exits, and suspicious activity are monitored at all times.
Keep only the test tab open during the exam and avoid using any other application — just like a real exam hall.
