## Overview

Tuition Management System is a role-based web app for students, tutors, and administrators. Users register or log in, students publish tuition requirements, tutors apply, and students select tutors; the system then supports scheduling, payments, feedback, messaging, notifications, and administration. The browser UI calls an Express API, which authenticates requests and accesses MySQL. The README provides no feature detail, so broader capabilities are included where frontend API methods and SQL files indicate them; backend details beyond the sampled routes are not verified.

Main entry points: [`backend/server.js`](https://github.com/obyduzzaman-abir/tuition-management-system/blob/main/backend/server.js) (HTTP API), [`schema.sql`](https://github.com/obyduzzaman-abir/tuition-management-system/blob/main/schema.sql) (MySQL application data), [`frontend/js/app.js`](https://github.com/obyduzzaman-abir/tuition-management-system/blob/main/frontend/js/app.js) (App workflow), [`frontend/js/api.js`](https://github.com/obyduzzaman-abir/tuition-management-system/blob/main/frontend/js/api.js) (API client)
