JAMB CBT Tutorial: How to Navigate the Computer-Based Test Interface

The JAMB CBT interface uses an eight-key navigation system that replaces the traditional mouse. Understanding this system before your exam gives you a significant advantage and helps you manage your time effectively during the 2-hour test.

The Eight-Key Navigation System

JAMB introduced a dedicated keypad device that replaces the mouse for answering questions and navigating through the exam. This eight-key device makes the process faster and more efficient once you understand how it works.

Key Interface Features

The Timer

The timer appears at the top of your screen and counts down from 2 hours (120 minutes). You will answer 180 questions across four subjects. Monitor this timer regularly to pace yourself properly.

Subject Navigation

You can switch between subjects at any time during the exam. You are not required to start with English Language or follow any particular order. Choose the subject you feel most confident in to build momentum.

Question Numbering

Each question is numbered, and you can see which questions you have answered and which remain unanswered. This helps you track your progress across all subjects.

Time Management Strategy

• Average time per question: About 40 seconds
• Total questions: 180 questions in 120 minutes
• Per subject: Approximately 30 minutes for 45 questions
• Tip: Do not spend more than 1 minute on any single question

Several platforms offer CBT practice software that simulates the actual JAMB interface:

• Practice using the official JAMB eight-key system
• Get familiar with the timer and subject switching
• Build speed and accuracy before exam day
• Use past questions from previous JAMB examinations
