Cloud Project

Cloud-Based Online Exam Portal

A scalable online examination platform with question banks, timed sessions, auto-evaluation and integrity checks.

Project overview

Faculty build question banks and schedule examinations; students take timed tests with autosave and resume; the platform evaluates objective questions immediately and publishes results with analytics per question and per student.

The cloud dimension is real here: examinations produce a sharp load spike at a scheduled time and almost no load otherwise, which is exactly the workload managed services exist for.

Problem statement

Conducting examinations for hundreds of students simultaneously overwhelms a single college server. Session loss mid-exam, no autosave, and manual evaluation of objective papers are all common failures.

Proposed solution

Store exam state server side with frequent autosave so a disconnection loses at most a few seconds of work, serve the application from a managed platform that scales on demand, and evaluate objective questions automatically while flagging integrity signals for review.

Key features

  • Question bank with difficulty tags and topic categorisation
  • Randomised question and option order per candidate
  • Server-side timer that survives refresh and reconnection
  • Autosave of every answer with resume after disconnection
  • Automatic evaluation with negative marking rules
  • Integrity signals such as tab switching and paste detection, surfaced for review rather than automatic punishment
  • Result publication with question-level difficulty analysis
  • Load-tested for concurrent candidates with documented results

System architecture

The flow below is what goes into your architecture diagram and the corresponding chapter of the report.

  1. Auth issues a session token bound to a scheduled exam window
  2. Exam service serves a candidate-specific randomised paper
  3. Answer service persists each response with a server timestamp
  4. Timer state lives server side so the client clock cannot be manipulated
  5. Evaluation service scores objective answers when the window closes
  6. Analytics service computes item difficulty and discrimination per question

Expected output

  • Working exam platform with faculty and student roles
  • Automatic results with per-question analytics
  • Integrity event log for review
  • Load test report showing behaviour under concurrent users

Suitable branches, difficulty and duration

Suitable branches

Difficulty level

Intermediate. Comfortable for a team where at least one member has worked in this stack before.

Development duration

8–10 weeks including documentation, tested and ready to demonstrate. Milestones are planned around your review dates.

Documentation, review, demo and viva support

Documentation support

Abstract, problem statement, literature survey guidance, system architecture, ER and UML diagrams, module descriptions, test cases and screenshots — prepared in your department format.

Project review support

Delivery is split across your review calendar so review one has a design and plan, review two has working modules, and the final review has the integrated, tested system.

Demo support

A rehearsed demo path, seeded sample data, a reset script, and a recorded walkthrough kept as a backup in case something fails in the review room.

Viva preparation

A written question bank for this domain, a code walkthrough session, and practice at explaining each module in your own words — because the examiner will ask you.

Customisation options

Colleges reject duplicate topics, so most projects are adjusted before we start. These are the usual directions for this one.

  • Add descriptive answer evaluation assisted by a language model with human review
  • Add webcam proctoring with periodic snapshots and consent handling
  • Add offline-tolerant mode that syncs when connectivity returns
  • Add adaptive testing that selects the next question from current performance
