CBT that still runs when the internet does not
Author an exam, publish it, and let students sit it — online in the browser, or offline on the Klasstack CBT app over a room’s own Wi-Fi when the network is down. Objective questions are marked by the same rules either way, and the scores land in your gradebook without anyone re-typing a mark.
What you get
Offline exams over the hall’s Wi-Fi
The Klasstack CBT app runs on one proctor laptop and serves the exam to a whole hall over local Wi-Fi — no internet for the whole sitting. It grades on the spot, then syncs every paper back to your school when the connection returns.
Reusable question banks
Build banks scoped to a subject, a class level or the whole school, organised by topic, and tag past-question banks by body and year — WAEC, NECO, JAMB, NABTEB or BECE.
Let AI do the typing
Paste a paper you already have and AI structures it into questions, options and answer keys as drafts. Nothing is saved until a teacher reviews it, and your wording is preserved.
Four question types, marked automatically
Multiple choice, true/false and short answer are scored the moment a paper is submitted. Essay questions come through to the teacher for marking.
Anti-cheat you control per exam
Turn on fullscreen, lockdown of copy/paste and right-click, one question per screen, a warning before a candidate can navigate away, and a hard close time — exam by exam, not school-wide.
Watch the hall in real time
Staff with the right permission see a live monitor of the exam, with anti-cheat flags — like a candidate leaving fullscreen or switching tabs — as they happen.
Scores that post themselves
On grading, scores post to the exam results and, when the exam is mapped to an assessment component, straight into the report-card gradebook.
Exam-day familiarity
A timer, a numbered question navigator and one-question-at-a-time delivery mirror the CBT format students meet in JAMB, WAEC and NECO — so the real thing feels routine.
There is a desktop app for offline exams
Klasstack CBT runs the hall from one laptop with no internet at all. Free with your plan, on macOS and Windows.
Frequently asked questions
- Can Klasstack run computer-based tests (CBT)?
- Yes. You author the exam and its questions, publish it, and students sit it on any device from the student portal. Multiple choice, true/false and short-answer questions are marked automatically on submission, and the scores flow into your gradebook.
- What happens if the internet goes down during an exam?
- You can run the whole sitting offline. The Klasstack CBT app holds the paper on one proctor laptop and serves it to the hall over local Wi-Fi — students just open a browser, no install. It marks locally, and syncs each paper back to your school when the connection returns.
- Can I stop students cheating during an online CBT?
- Each exam has its own delivery and anti-cheat settings: enforced fullscreen, blocked copy, paste and right-click, one question per screen, a warning before leaving the page, and a hard close time. Tab-switches and fullscreen exits are flagged to a live proctor monitor as they happen.
- Do I have to type every question by hand?
- No. You can type questions in, bulk-paste them, or paste a paper you already have and let AI structure it into questions and answer keys. AI output is always a draft a teacher reviews before it is saved.
- Can I reuse questions across terms and classes?
- Yes. Question banks are reusable and can be scoped to a subject, a class level or the whole school, organised by topic, and shared with other teachers. Past-question banks can be tagged by examining body and year.
- Does it help students prepare for JAMB and WAEC CBT?
- Yes. Practising on screen with a timer, a question navigator and one-question-at-a-time delivery — the same shape as JAMB, WAEC and NECO CBT — helps students get comfortable well before the real assessments.
