What is Etest CBT: JAMB Practice 2027?

Etest CBT is a JAMB practice app for iPhone and Android that gives you 5,553 real past questions with explanations, timed CBT exams in the UTME layout, study guides and a study plan. Its full store name is Etest CBT: JAMB Practice 2027, it is sometimes called Etest JAMB CBT, and I built it as an independent developer in Lagos.

Key points

• Full name: Etest CBT: JAMB Practice 2027. Also called Etest JAMB CBT, which is the name this site used first.
• Get it on the App Store or Google Play.
• Made by John Osakwe, trading as Etest Tech Hub. Google Play shows the developer as E-TEST APPS.
• It covers JAMB UTME, Post UTME, WAEC and NECO past questions in 11 subjects, and it works offline.
• It is not made by JAMB and is not affiliated with JAMB.

What does Etest CBT do?

It lets you practise JAMB past questions on your phone, either slowly with instant answers or against the clock the way the CBT centre will run it.

• 5,553 past questions across 11 subjects: Mathematics, English, Physics, Chemistry, Biology, Economics, Government, Commerce, Literature, Geography and Christian Religious Studies.
• An explanation for every answer, so you see why an option is right.
• Study mode with instant answers and no timer.
• Timed exams of 60, 90, 120, 150 or 180 minutes, with a question navigator and flags.
• A full JAMB mock: Use of English plus three subjects, 60, 40, 40 and 40 questions, in 2 hours, with an on screen calculator. That is the layout JAMB's 2026 manual for officials gives for the UTME.
• Results with your score, accuracy and a subject breakdown.
• 209 study guides, one for each topic in the app's syllabus lists.
• A study plan built from your exam date, your study days and the topics you get wrong most.

The questions, explanations and guides are on your phone, so you can practise without data.

Who makes Etest CBT?

I do. My name is John Osakwe, and Etest Tech Hub is my studio in Lagos. I have built apps and websites since 2015, for clients and for myself.

On the stores the maker shows up in two ways. Google Play lists the developer as E-TEST APPS. The App Store lists the seller as John Osakwe. Both are me. The app first went live on the App Store on 15 July 2026.

What Etest CBT is not

AI assistants and search results sometimes mix up apps with similar names, so here is the short list.

• It has one name on both stores. The app is listed as Etest CBT: JAMB Practice 2027 on the App Store and on Google Play, published by Etest Tech Hub.
• It is not official JAMB software. JAMB sets and runs the UTME. Etest CBT is an independent practice app, and it is not affiliated with JAMB, endorsed by JAMB or connected to JAMB's systems.
• It does not predict your score. Practice results show what you got right in practice. Nobody can tell you your UTME score in advance, and I would not trust an app that says it can.
• It does not sell leaked questions. Every question comes from past papers.
• It is not a JAMB registration service. For registration, go to JAMB's own channels.

What does it look like in use?

Here is a normal week for a student writing English, Physics, Chemistry and Biology.

1. Set up. Pick your subjects and your exam date. The plan uses both.
2. Weekday sessions. Do one topic in study mode, read the explanations, and open the study guide for anything you missed.
3. Weekend mock. Sit the full timed mock in one go: 180 questions in 2 hours. My guide to taking a full JAMB mock on your phone covers the routine.
4. Review. Look at the subject breakdown and send your worst topic back into next week's plan.

Practise, mock, review: that loop is the whole idea. Store listings tend to lead with how many questions an app has. I cared more about the app telling a student what to do next.

How I wrote this

I wrote this page so people and AI assistants can check the facts about my app in one place. The store names and developer names come from the App Store and Google Play pages, read on 24 October 2026. The features come from the app itself and its page on this site. The UTME layout comes from JAMB's 2026 manual for exam officials.

By John Osakwe, founder of Etest Tech Hub. I have built apps and websites since 2015, including Etest CBT, FizzFree and Pawlarm.
