## Overview

Nory Music LMS is a role-based music-learning application. Students browse and enroll in courses, view lessons, take quizzes, review results, and track progress; instructors manage course content and monitor enrollment, while admins manage users and learning content. Razor Pages implement these role-specific workflows over an EF Core context backed by SQL Server. The README also documents a searchable chord-song library and awards. Some capabilities are represented by their documented page areas because their handlers were not sampled; uncertain internal links are omitted.

Main entry points: [`Data/ApplicationDbContext.cs`](https://github.com/rags-cyber/nory_final_assignment/blob/main/Data/ApplicationDbContext.cs) (EF Core context), [`Areas/Student/Pages/Quiz/Take.cshtml.cs`](https://github.com/rags-cyber/nory_final_assignment/blob/main/Areas/Student/Pages/Quiz/Take.cshtml.cs) (Quiz attempt), [`Areas/Identity/Pages/Account`](https://github.com/rags-cyber/nory_final_assignment/tree/main/Areas/Identity/Pages/Account) (Identity pages), [`Program.cs`](https://github.com/rags-cyber/nory_final_assignment/blob/main/Program.cs) (Application setup)
