Quick answer

You don’t need to be a computer expert to pass the JAMB CBT — you only need a few basics: how to use the mouse to select answers, how to move between questions, how to flag and review, and how to submit. This guide walks a first-timer through the exact steps, and the best way to get comfortable is to practise on a real CBT interface before exam day.

What "CBT" actually means

JAMB switched to the Computer-Based Test (CBT) years ago, so you answer every question on a computer instead of on paper. The good news: you don’t type essays and you don’t need any special computer skill. If you can move a mouse and click, you can take the JAMB CBT. This guide walks a first-timer through exactly what happens on screen.

The only skills you really need

  • Using the mouse to click the option you want.
  • Clicking buttons to move between questions.
  • Reading carefully on a screen (a little different from paper — practice helps your eyes adjust).

That’s it. You will not be asked to type long answers, use software, or do anything technical.

Logging in and starting

At the centre, your identity is confirmed by biometric (fingerprint) verification — this is the only way you’re admitted, and it also serves as your attendance. The system then loads your details and your exam. Before you begin, read the on-screen instructions carefully; take a few seconds to see where everything is.

The question screen

You’ll see one question at a time with four options labelled A–D. Click the option you want and it becomes highlighted — that’s your answer recorded. On the screen you’ll also see the timer counting down and the question numbers so you know where you are.

Use the Next and Previous buttons (or click a question number) to move around — you can revisit any question. You can flag a hard question to come back to, and a review screen shows which questions you’ve answered and which are still blank. This is how you make sure nothing is left unanswered.

Submitting your exam

When you’re done you click Submit; if you run out of time the system submits automatically. Before submitting, use the review screen to confirm every question has an answer — there’s no negative marking, so never leave a blank.

If something goes wrong

If your screen freezes or there’s a power issue, don’t panic and don’t touch other machines — raise your hand and tell the invigilator immediately; interrupted time is normally sorted out. If your fingerprint won’t verify at entry, you’ll be recaptured at the centre rather than turned away. Note that you may not bring a calculator; do calculations mentally or on any rough sheet the centre provides — confirm this at your centre.

The #1 tip: practise on a real CBT first

Students who practise on a CBT interface consistently outperform those who only read from books — because on exam day the screen already feels familiar. Do free CBT practice and a daily Daily Challenge so selecting answers, flagging and reviewing become second nature well before you walk into the hall.

Frequently asked questions

Do I need to be good with computers to pass JAMB?
No. You only need to use a mouse to click your answers and buttons to move between questions — there’s no typing of essays and nothing technical. Basic skills are enough, and practising on a CBT interface makes it feel easy.
Can I use the keyboard in the JAMB CBT?
You mostly use the mouse to select answers and navigate. Some systems allow a few keys, but you never need to type long answers. Focus on getting comfortable clicking options and moving between questions.
Is there a calculator on the JAMB CBT screen?
You cannot bring your own calculator, and JAMB generally expects mental calculation. Some centres provide rough paper; confirm at your centre. Practising mental maths and estimation under time is the safest preparation.
What happens if the computer freezes during my exam?
Stay calm, don’t touch other machines, and alert the invigilator immediately. Technical interruptions are normally handled and lost time adjusted. The worst thing you can do is panic or try to fix it yourself.
Can I change my answer in the JAMB CBT?
Yes. You can go back to any question, change your selected option, flag questions to revisit, and use the review screen to check for blanks before submitting.
