Help
Efiko is exam practice for students sitting JAMB UTME and WAEC WASSCE. This page answers the things that actually go wrong, in roughly the order they happen to people. If yours is not here, write to ask@efiko.me and a person will read it.
Last updated 9 October 2026.
Nearly every problem is the sign-in code. It lasts ten minutes, it works once, and asking for a new one cancels the one before it. If a code was refused, ask for another and use the newest email — that is always safe, and it costs you nothing.
How do I get Efiko?
Open efiko.me/get on the phone you want it on. It works out whether you are on Android or iPhone and takes you straight to the right store. One address, and it is the one to send to a friend.
If you would rather search the store than tap a link, search Efiko past questions. The full name is what the stores match on.
You can also skip installing entirely. Open efiko.me/app in any browser, on a phone or a laptop. Nothing to download, so it is the one to use when a school computer will not let you install anything or your phone has no room left, and it is the fastest way to see whether Efiko suits you.
All three are the same app and the same account. Sign in and whatever you did on one shows up on the others.
The code did not arrive
Efiko has no password. You type your email address and we send a six-digit code to it. When one does not turn up, it is almost always one of these four.
- It is in spam. Gmail also files it under Promotions sometimes. Search your mail for Efiko rather than scrolling.
- The address has a typo in it. This is the one that catches people, because a typo that is still a valid address gets no error anywhere: the code is sent, to an inbox nobody reads. Tap Use a different email and type it again slowly.
- Two codes arrived and you used the first. Only the newest one works. Asking for another cancels the one before it, so if there are two emails, the second is the live one.
- You have asked five times in an hour. That is the limit per address. Wait an hour, or write to ask@efiko.me.
The code was refused
A code stops working for three reasons: it is more than ten minutes old, it has already been used once, or it has been typed wrong five times. In all three cases the fix is the same — ask for a new one. Nothing about your account or your practice is affected by a refused code, and there is no penalty for asking again.
I left the app to read my email
If you switch to your email app and come back to find Efiko showing the address screen again rather than the box for the code, nothing has gone wrong with your account. Ask for a new code and type it in.
If your phone shows the code in the notification itself, reading it from there without opening your email app avoids the trip entirely.
We share one phone
Plenty of students share a handset with a sibling or use one at school. Efiko is built for that, and there is one rule worth knowing before it surprises you.
- Work done while signed in belongs to that address. When somebody else signs in on the same phone, the first student's practice is cleared off the handset. It is not lost. It is on the server under their own address and it comes back the moment they sign in again, on that phone or any other.
- Work done before anyone signs in belongs to whoever signs in first. It is taken into their account. So if you practise without an account and then hand the phone to a friend who signs in, that practice becomes theirs and there is no way to move it afterwards.
On a shared phone, then: sign in before you start, not after.
Does it work without data?
Yes. Every question, every explanation and every diagram is inside the app, so practice, mock exams and the marked answers all work with no connection at all and cost you no data.
Three things need a signal: signing in, carrying your work to another phone, and picking up corrections. Reporting a question does not: it is saved on your phone and sent the next time you are online, so it costs you nothing to write one with no data. That last one matters and is easy to miss — when we fix a wrong answer or a wrong diagram, it reaches your phone the next time you open Efiko with a connection. You do not have to update the app from the store.
A question looks wrong
Tap the flag at the top of the question and say what is wrong. It takes a few seconds and it is the most useful thing anybody sends us.
If the key really is wrong we withdraw the question. It stops being served, and it stops counting against your accuracy — including in the answers you have already given, so a question you got "wrong" against a bad key is put right rather than left on your record. The withdrawal reaches every phone without an app update.
We would much rather read a report that turns out to be mistaken than leave a wrong question standing, so send it even if you are not certain.
Redoing the questions I got wrong
A question that beats you and never comes back is a mark you will lose again, so Efiko offers the ones you missed back to you. It is the card on the home screen that says Take another look.
- It holds the questions you missed in your last daily ten. Extra practice does not feed it, on purpose: a hundred questions and forty misses is not a review, it is another exam.
- It appears the day after that round, not the same day, and it waits however long it takes you to come back. Miss four on Monday, open Efiko on Friday, and they are still there.
- The options are moved around, so you cannot remember the answer by its position.
- You get one look at each question, whether you get it right or wrong the second time. The idea comes back through ordinary practice instead, as a different question.
- A clean ten wipes it. A perfect round is supposed to clear the slate, so it does.
- It is per exam. Your JAMB misses are not offered while you are studying WAEC.
If you have not been seeing it: until October 2026 that card sat near the bottom of the home screen and disappeared as soon as you started the day's quiz, so most people never met it. It is at the top now, and it stays all day. You need the newest version of the app from your store for that.
What the predicted score means
The number on the home screen is a projection out of four hundred, built from the questions you have actually answered, subject by subject. It is Efiko's arithmetic on your own work.
It is not a promise and it is not a JAMB number. Nobody can tell you what you will score. It also tends to dip when you start a harder topic, which is the model noticing the new material rather than you getting worse — it settles again as you work through it.
Practice where you chose the topic does not move it. When you tap Practise a topic and pick your own topics from the syllabus, those rounds are left out of the number on purpose. The real exam does not let you choose which topics come up, so a score built from the ones you picked would be a flattering answer to a question nobody asked. The app says so on every screen of a topic round.
Everything else about that practice still counts: your XP, your streak, your badges, and the days towards the Efiko badge. It is only the prediction that stays still, because only the prediction is a claim about a whole paper.
What it costs
Nothing. Efiko is free, with no in-app purchases and no adverts.
Access runs to the end of the exam season. When a new one starts, Efiko asks you to carry on, and your practice, your streak and your predicted score all stay exactly as they are.
What Efiko keeps, and deleting it
The full answer is at efiko.me/privacy, written so it can be checked against the app. The short version: an email address, your answers, and the few settings that let a new phone carry on — your nickname and your phone number if you entered one. If you send work to a teacher, the name you give for their register goes with it. Efiko never asks which school you attend.
To delete everything, open Profile → Account → Delete My Account. It asks for a code sent to your email first. That is deliberate: a phone left unlocked on a desk is already signed in, and deleting a season of work should need something only you can reach.
Still stuck
Write to ask@efiko.me. It helps a lot if you say which phone you are using, what you were doing, and what you saw on the screen.
The version number is in Profile → About Efiko, and quoting it usually saves a round of questions. If you are locked out of the app, write from the address you signed up with where you can — it is the fastest way for us to find the account.
