How does the browser lockdown work?

The exam launches in a locked-down mode that disables tab switching, copy-paste, printing, and new browser windows. Attempting to switch tabs or open developer tools records a violation event. The exam is submitted automatically if too many violations accumulate.

How is item analysis done?

Item analysis evaluates each question's quality using discrimination index (did high scorers answer it correctly?) and difficulty index (what percentage answered correctly?). Questions with poor discrimination or extreme difficulty are flagged for review and possible removal from the live bank.

How are certificate verifications handled?

Each certificate has a unique QR code and verification URL. Third parties (employers) can scan the QR or visit the URL to verify the certificate's authenticity, candidate name, exam name, score, and issue date from the platform's certificate registry.

The Challenge

Why building a Exam Platform from scratch is hard

Building a Online Exam & Assessment Platform from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing exam platform-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Exam Platform needs

ProjectCode generates a production-ready Exam Platform with all the modules your team needs from day one.

Question bank with categorization and difficulty tagging

Exam creation with timed sections and question randomization

Proctoring: AI video monitoring and tab-switch detection

Multiple question types: MCQ, essay, coding, matching

Auto-grading for objective questions

Detailed result reports with percentile and skill breakdown

Certificate generation on passing

Bulk exam invitation and cohort management

Architecture

How it's built

The generated Exam Platform follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for exam platform workflows

NestJS REST API with dedicated exam platform modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all exam platform entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live exam platform status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Exam Platform

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

questions (id, subject, topic, type, difficulty, content jsonb, options jsonb, correct_answer, explanation, workspace_id)
exams (id, name, questions jsonb, duration_minutes, passing_score, randomize, proctored, attempts_allowed, workspace_id)
attempts (id, exam_id, candidate_id, started_at, submitted_at, answers jsonb, score, passed, percentile, certificate_id)
candidates (id, name, email, cohort_id, invitation_sent_at, workspace_id)

FAQ

Common questions about building a Exam Platform

During the exam, the candidate's webcam is monitored by AI that detects anomalies: looking away from the screen, multiple faces detected, or unauthorized persons entering the frame. Flagged events are recorded as clips for human review. Severe violations can automatically terminate the exam.
