Extend an Existing MCQ Platform to mock exams

We have already developed a fully functional online question bank platform . The system includes:

* Admin panel for complete content management
* User dashboard for students
* Structured hierarchy: Subject → System → Category → Topic
* Full MCQ entry system (question stem, options, explanations, question IDs, etc.)

We are now looking to extend this existing platform to support NBME-style assessment exams. This is not a project from scratch — most of the backend and frontend are already built. The task primarily involves modifying and extending current features.

Scope of Work:

1. Exam Mode (NBME-style)

* Create timed assessments (e.g., 40-question blocks)
* Fixed exam structure (not random continuous QBank mode)
* Ability to group questions into predefined exams
* Timer functionality (with auto-submit)

2. Question Mapping

* Use existing question bank
* Allow admin to assign specific questions into exam blocks
* Option to tag questions as “assessment eligible”

3. Exam Interface (Frontend)

* NBME-style UI/UX (clean, distraction-free)
* Question navigation panel (mark, review, next/previous)
* Block-based navigation

4. Result & Review System

* Score report after exam completion
* Percentage, correct/incorrect breakdown
* Review mode (with or without explanations toggle)
* Optional delayed explanation release

5. Admin Panel Enhancements

* Create and manage assessment exams
* Assign questions to specific exams/blocks
* Control exam settings (time, number of questions, randomization if needed)

6. Performance Tracking

* Basic analytics (score history, performance trends)
* Per-subject/system breakdown (if feasible using existing structure)

Technical Notes:

* Existing system is already built (details will be shared with shortlisted candidates)
* Goal is to reuse current architecture, not rebuild
* Clean, scalable modifications are required
* Code quality and maintainability are very important

⸻

Ideal Candidate:

* Experience with EdTech platforms or MCQ-based systems
* Familiarity with exam engines or test-taking interfaces
* Strong frontend + backend integration skills
* Ability to understand and extend an existing codebase efficiently

⸻

Deliverables:

* Fully functional NBME-style exam mode integrated into current platform
* Updated admin controls for exam creation
* Smooth user experience across dashboard and exam interface
* Bug-free, tested implementatio
