You can practise IJMB questions on an Android phone with no data at all — as long as the app keeps its question bank on the phone instead of on a server. That single difference separates a genuinely offline app from one that only looks offline until your bundle runs out in the middle of a timed paper. Try free IJMB past/practice questions.
Below are five offline Android apps for IJMB CBT practice, ranked by how useful they are to a Nigerian A-level candidate studying mostly alone. FreshNote sits at the top. One honest note before the list: these are practice tools. None of them contains leaked papers, and none of them guarantees you a grade or an admission.
How this ranking was put together
The order is a judgement, not a survey result. Each app was weighed against five things that actually matter when you are revising on a phone:
- It works with mobile data switched off after installation.
- It covers IJMB or JUPEB content, not only JAMB.
- It shows you answers, and ideally explanations, without going online.
- It lets you answer under a timer, the way a computer-based test feels.
- It fits on a phone with limited storage and does not demand a permanent connection.
App stores change constantly. Treat the descriptions here as a starting point and confirm the current version yourself before you rely on any app for weeks of revision.
The five apps, ranked
1. FreshNote — the best all-round offline IJMB app
FreshNote is built around IJMB and JUPEB past questions rather than around JAMB, and that is the main reason it leads this list. Most Nigerian practice apps treat A-level candidates as an afterthought: you install them, then discover the questions stop at WAEC level. FreshNote's content sits where IJMB students actually are.
The parts that matter for offline study:
- Past questions stored on the device. Install once, then practise with data off.
- Multiplayer or challenge mode. Useful when reading alone starts to feel flat — you can compete with friends instead of staring at the same screen.
- Note-jotting inside the app. You can record why you missed a question without hunting for a separate notebook.
- A grade calculator. Handy for seeing how a set of scores translates into points, so you know whether you are close to your target or far from it.
A practical way to use it: pick one subject, answer a timed block, then spend the same amount of time reviewing only the questions you got wrong and writing a short note on each. That review half is where the marks come from. Students who only answer questions and never look back tend to plateau.
What FreshNote will not do is tell you the current IJMB syllabus, exam format or grading rules. Check those with the IJMB board or your study centre. Download it from Google Play and read the listing description before you commit — feature lists and ratings change.
2. A dedicated IJMB or JUPEB past-question app from another publisher
There are a few smaller apps aimed at A-level candidates, usually published by individuals rather than big companies. Some are free, some charge a small fee, and quality varies a lot. Before you keep one, check that it lists IJMB subjects on the description, that it was updated recently, and that a quiz actually opens with your data switched off. If answers only appear when you are online, it is not an offline app — it is a website in a wrapper.
3. A JAMB CBT practice app, used only as a timing drill
JAMB practice apps are everywhere, many work offline, and their interface is close to what a computer-based test feels like. Use them for that and nothing else. Their subject content is pitched at O-level, so it will not carry you through IJMB Biology or Chemistry. Think of them as a stopwatch with buttons, not a syllabus.
4. AnkiDroid for flashcards you build yourself
AnkiDroid is a free, open-source flashcard app that runs entirely on the phone once your decks are loaded. It is excellent for the things you have to memorise: definitions, formulae, enzyme names, key dates in a literature text. The catch is that nobody has built an IJMB deck for you. You create the cards, which takes time but is itself a form of revision.
5. Any offline PDF reader, plus past-question files you already have
The least exciting option and the most reliable. A PDF stored on your phone opens whether you have network or not, and it cannot fail because a server is down. What you lose is the timer, the automatic scoring and the explanations — unless the file includes them. Our main guide on how to get IJMB and JUPEB past questions and answers explains where these files come from and how to check they are complete.
How the five compare
| App | Works fully offline | IJMB-specific content | Answers shown offline | Timed practice |
|---|---|---|---|---|
| FreshNote | Yes | Yes | Yes | Yes |
| Other IJMB/JUPEB apps | Usually | Usually | Depends on publisher | Often |
| JAMB CBT apps | Yes | No | Yes | Yes |
| AnkiDroid | Yes | Only what you build | Yes, on your own cards | No |
| PDF reader | Yes | If your file is IJMB | Only if the file has answers | No |
Test any app for true offline use before you depend on it
- Install the app while you still have data, and open it once so it can finish setting itself up.
- Turn on airplane mode, or switch mobile data off completely.
- Close the app from your recent-apps list, then reopen it.
- Start a quiz and answer a few questions.
- Submit and check whether the answers and explanations still appear.
- Check how much storage it has taken, and whether it still shows adverts that need a connection.
If any step fails, the app is not offline for your purposes. That test takes five minutes and saves weeks of frustration.
Mistakes students make with offline practice apps
- Answering questions without a timer, then being surprised by the clock in the real hall.
- Practising only the subjects they already like.
- Skipping the review of wrong answers, which is the part that raises the score.
- Assuming app questions are the actual exam paper. They are practice, nothing more.
- Installing four apps and finishing none of them. One app, worked through properly, beats a full folder.
What these apps can and cannot do for you
They can give you volume: hundreds of questions you can answer on a bus with no network. They can build the habit of reading a question under time pressure. They can show you where your weak topics are.
They cannot replace your syllabus or your textbooks, they cannot confirm the current exam format, and they cannot promise an admission. Anything official — subject combinations, registration windows, grading — comes from the IJMB board or your study centre, not from an app description.
Questions students still ask
Is IJMB written or computer-based?
IJMB examinations have traditionally been written papers rather than computer-based tests, which is different from JAMB. That is exactly why timed practice on a phone is still worth doing: it trains speed and accuracy, whatever the format. Confirm the current arrangement with the IJMB board or your centre before you plan around it.
Will an offline app still eat my data?
Sometimes. Background updates, adverts and analytics can all use a connection quietly. Restrict background data for the app in your phone settings, and turn mobile data off entirely during a practice session so nothing interrupts you.
If you are going to install one app this week, make it the one built for the exam you are actually sitting, test it in airplane mode, and give it three timed sessions before you judge it. Everything else on this list exists to fill a gap that one might leave.
