How the JAMB CBT System Works
Before we dive into mistakes, you must understand how the JAMB CBT system operates:
-
Dedicated Computers: Each candidate is assigned a workstation for the exam.
-
Secure Software: The CBT software locks down the system to prevent cheating.
-
Automatic Timing: The exam timer is built-in and cannot be paused.
-
Monitoring & Tracking: The system logs unusual activity such as window switching or external program access.
-
Data Protection: Any attempt to manipulate the system can result in a freeze, logout, or flagged session.
Why Understanding This Matters
Many shutdowns are caused by panicked students trying to “fix” what they think is a system issue. Knowing how the software works can reduce mistakes and prevent unnecessary stress.
Mistake 1: Pressing Random Keyboard Shortcuts
Common Shortcut Errors
Candidates often press the following keys when they panic:
-
Ctrl + Alt + Delete
ADVERTISEMENTADVERTISEMENT -
Alt + Tab
-
Windows Key

F5 or Esc repeatedly
Consequences
| Shortcut | Consequence |
|---|---|
| Ctrl + Alt + Delete | Triggers system lock or freeze |
| Alt + Tab | Switches windows, logs out candidate |

Correct Behavior
