Online Examination & Assessment Platform
Our client, an education and training provider, needed an online examination platform that could run timed, proctored tests for large groups of students without relying on physical test centers.
The primary challenge was building an exam engine that supported varied question types, enforced time limits and proctoring rules reliably, and graded objective questions automatically to reduce manual work.
Managing exam integrity, handling connectivity interruptions mid-test, and generating accurate reports at scale were significant technical hurdles.

Challenge
Our client, an education and training provider, needed an online examination platform that could run timed, proctored tests for large groups of students without relying on physical test centers.
The primary challenge was building an exam engine that supported varied question types, enforced time limits and proctoring rules reliably, and graded objective questions automatically to reduce manual work.
Managing exam integrity, handling connectivity interruptions mid-test, and generating accurate reports at scale were significant technical hurdles.

Solution
Zyber Zing designed and built an online examination platform that lets institutions run secure, timed assessments remotely.
Built with React on the frontend and a Node.js and PostgreSQL backend, the platform manages question banks, exam sessions, and grading in one system.
WebRTC-based webcam proctoring and session-security rules help maintain exam integrity, while auto-save keeps progress intact through brief connectivity drops.
Objective questions are graded automatically, and a dedicated reporting engine gives administrators exportable results as soon as an exam session closes.
