Everything you need between now and results day.
Theorem replaces scattered PDFs and photocopied past questions with one focused app built around how JUPEB is actually examined.
Real CBT simulation
Timed, computer-based practice that mirrors the actual JUPEB exam interface, so exam day feels familiar instead of foreign.
Past questions by subject and year
Pick a subject, then a year, then work through that paper -- answer first, and Theorem reveals the correct answer and explanation after.
Learn offline, anywhere
Download a subject once and practice without spending data -- on a bus, in a hostel with no signal, or anywhere study happens.
Track your progress
An analytics view of your accuracy and attempts across subjects, so you can see which papers still need work before you sit the real thing.
Organized notifications
Updates are grouped by category -- new past questions, exam reminders, account -- instead of one long, noisy feed.
Built for the JUPEB syllabus
Every question set is scoped to the JUPEB curriculum, not a generic bank of unrelated exam content.
From install to exam-ready, in four steps.

Download and set up your profile
Install Theorem, tell it which JUPEB subjects you're taking, and you're ready to start.
- 02
Choose a subject and a year
Every past question is organized by subject first, then by year -- so you practice full papers, not a random mix.
- 03
Sit the paper in CBT mode
Answer under timed, computer-based conditions that match the real JUPEB exam before any answer is revealed.
- 04
Review, then track your progress
See the correct answer and explanation for anything you missed, and watch your accuracy improve on the analytics tab.
A closer look inside the app.
Every screen is built around one goal: get you from “studying” to “exam-ready” as fast as possible.
From our private beta cohort.
A small group of JUPEB candidates tested Theorem before launch. Here's what stuck with them.
“Practicing in actual CBT format took the fear out of exam day. I knew exactly what to expect before I sat down.”
“Being able to download a subject and practice on the bus with no data was the whole reason I kept using it.”
“The analytics tab showed me exactly which subject was dragging my average down. I fixed it two weeks before exams.”

Questions, answered.
What is JUPEB, and who is Theorem for?
JUPEB (the Joint Universities Preliminary Examinations Board) runs a one-year programme that leads into direct entry admission at Nigerian universities. Theorem is built for students on that programme who need focused, exam-accurate practice.
Does Theorem really work without internet?
Yes. Once you download a subject's question bank, you can practice, sit CBT mock exams, and review answers without spending mobile data or needing a connection.
How does the quiz mode work?
You answer each question first. The correct answer and a short explanation are only revealed afterward, so practice sessions test recall the same way the real exam will.
Is Theorem available on iPhone?
Theorem is launching on Android first. An iOS version isn't ruled out, but there's no confirmed date yet.
When does Theorem launch?
Theorem is on track for release on the Google Play Store on 5 November 2026.
How does the premium subscription work?
Premium unlocks the full past-question library and unlimited CBT mock exams for ₦4,000 across 9 months, paid securely through Paystack.
