Exam Clock

Matrix Exam Clock

Matrix Exam Clock is a user-friendly exam information and clock system that can be set up in seconds. It supports up to four exams running simultaneously in the same room and provides a clear, professional display for students and invigilators.

It runs fully offline after activation and does not require an internet connection during use.

Important Note for IB Schools

Matrix Exam Clock uses the same clear layout and style as the IB version of Matrix Exam Clock, making it a great way for teachers and students to become familiar with the format before official examinations.

It can be used for mock exams, internal tests, or any other examination. Matrix Exam Clock is not limited to IB examinations and works as a standalone exam display system for any school or examination setting.

If the IB version of Matrix Exam Clock for the relevant session is already available, you can even use that for a mock exam. Just cheat a little with the date and select the date of the corresponding official IB examination, so the correct subject and exam information are displayed. Or simply use Matrix Exam Clock for the mock — it's entirely up to you.

Enter Exam Details

Click the Exam 1 tab and enter the details for your first exam:

Subject, Level, Paper, Duration, and Style.

The timeline is calculated automatically from the duration you provide.

Customise the Timeline

For each exam individually, you can choose which timeline checkpoints are displayed on the main screen.

Simply tick or untick:

• Start Reading
• 30 Minutes Remaining
• 5 Minutes Remaining
• +25% Extra Time

This allows each exam display to match the specific requirements of that examination.

Add Notes

Use the Extra Info box to enter private notes or reminders for the invigilator.

These notes are only for the invigilator's reference and are not shown on the student display.

Add More Exams

Once Exam 1 is completed, the Exam 2 tab unlocks.

Additional exams can be added to the screen, but they must be populated in sequential order:

1 → 2 → 3 → 4

Present to the Room

Once all exams have been entered and details have been verified: Click Hide Exam Details.

The control panel smoothly collapses, maximising the timeline display across the entire screen.

Matrix Exam Clock is now ready for students.

Set the Actual Start Reading Time

At the top right of the screen, you can adjust the actual Start Reading Time.

By default, the Start Reading Time is set to five minutes before the scheduled start time. If you do not use reading time, simply set it to five minutes before the actual exam start time.

For a cleaner display, click Hide Actual Start Reading Time.

What to Expect During the Exam (Visual Cues)

The display is designed to guide the room automatically without requiring manual updates.

Upcoming Times

Future events are displayed using a bold, clear font that can be easily read from across the room.

Current Key Moments

When an important event occurs—such as:

• Start Reading
• Start Exam
• 30 Minutes Remaining
• 5 Minutes Remaining
• End Exam

the corresponding time pulses red for one minute to alert the invigilator.

Passed Times

Once a moment has passed, it fades into a subtle background block, making completed phases easy to identify.

Important Note

Ensure your computer's Power & Sleep settings are configured so the display does not turn off or enter sleep mode while the timer is running.

For a full-screen experience and to permanently save your license key on mobile devices, we highly recommend using your browser's "Install" or "Add to Home Screen" option.
■ Offline Operation: Once activated online, the desktop and web applications save the required verification data locally, allowing them to operate fully offline.

■ License Storage & Re-Activation: Desktop applications (Windows and macOS) save your license permanently. The Web Application stores your activation in your browser's local storage.
