The examination platform for universities and enterprises.
SERTUS runs secure theory and practical examinations at institutional scale — deployed on-premise, cloud, or hybrid, and trusted for high-stakes evaluation.
Q3. Analyse the average and worst-case time complexity of quicksort with a randomised pivot. Illustrate with a partition trace on the array [8, 3, 7, 1, 9, 4, 2, 6] and justify your reasoning.
Randomised quicksort selects a pivot uniformly at random from the current partition,
which yields an expected running time of Θ(n log n) irrespective of input ordering...
The questions your evaluation committee will ask.
Can this scale to our institution?
Tens of thousands of concurrent candidates across campuses, on cloud or on-premise infrastructure.
Is it secure enough for high-stakes exams?
Identity verification, session integrity, hash-chained audit logs, and encrypted submissions end-to-end.
Does it support practical examinations?
Station-based practicals with observer sign-off, media capture, and command-output submissions.
Can we deploy on-premise?
Cloud, on-premise, and hybrid deployments — with full control retained by your IT team.
This is what your candidates see.
A distraction-free, accessible examination interface designed for high-stakes performance — with continuous auto-save, offline tolerance, and screen-lock integrity.

Creating examinations is simple.
Assemble papers from institution-wide question banks against blueprint coverage, route drafts through moderation, and reuse validated items across sessions.
Manage thousands of candidates across campuses.
A single control centre for the examination calendar, hall allocations, delegated administration, and readiness across every department.

Supervise at institutional scale.
A dedicated invigilation workspace surfaces meaningful signals — focus loss, identity mismatches, connectivity — without overwhelming supervisors.
Digital evaluation saves weeks per session.
Anonymised, rubric-driven marking with blind, double, and triple valuation, moderation, and complete audit trails — feeding straight into result processing.
Depth-first search maintains a stack of active vertices. On visiting v, we recurse into each unvisited neighbour...
The algorithm's correctness follows from the white-path theorem: v is a descendant of u in the DFS forest iff...
Leadership gets meaningful insights.
Question-level analytics, cohort performance across campuses, and signed board reports — exportable and ready for governing councils.
Every role gets a workspace built for their work.
Switch between roles — the navigation, primary metrics, tables, and actions transform. SERTUS is a complete ecosystem, not one dashboard with different labels.
Built for high-stakes examinations.
Every examination on SERTUS moves through a defined chain of controls — identity verification, session integrity, encrypted submission, digital evaluation, and hash-chained audit logs.
