The Challenge: Why English Practice Diagnostic Was Built
Language learners often struggle with rote memorization methods, which fail to address underlying grammatical principles. Static question banks offer limited variety, leading to memorization rather than understanding. The English Practice Diagnostic was built to address these challenges by providing a dynamic, AI-powered platform that generates adaptive, high-quality questions tailored to individual needs.
Core Architecture & Technical Stack Deep-Dive
The English Practice Diagnostic is built on a robust technical stack, including Django 5, Python 3.12, and OpenRouter API for AI-powered question generation. The platform utilizes SQLite for data persistence, ensuring that question banks and active test sessions survive container restarts. The architecture is designed for resilience, with automatic fallback to a local question bank in case of API downtime.
Key Components
- Frontend Layer: Server-rendered Django templates enhanced with Bootstrap 5 for a responsive and user-friendly interface.
- Application Layer: Django 5.x running under Gunicorn WSGI for efficient request handling.
