An educational web application where students can answer topic-based questions, complete timed practice sessions, and track their preparation progress through an intuitive personal dashboard.
Integrated with Stripe subscriptions to offer tiered membership access, providing self-paced study resources backed by Express REST services.
The platform was created to deliver an accessible online practice environment for students. It combines categorized question banks, instant answer verification, historical score tracking, and automated recurring billing for premium study modules.
Students needed a distraction-free environment to practice question sets, understand their weak areas, and maintain study momentum. The business required an automated subscription mechanism to gate premium question banks without manual access management.
The application provides a seamless flow from subscription sign-up to daily practice question sessions.
I developed the interactive quiz taking interface in React, built the student analytics views, authored backend API endpoints, and integrated the Stripe webhook listeners that update student subscription statuses.
To safeguard test integrity, correct answers and detailed explanations are stored on the server and only delivered to the client after a question submission is registered. Client session states are cached locally so interrupted quiz sessions can be resumed without loss of progress.
