# pratyushwinorlearn/learning-management-system architecture

> Architecture diagram of the GitHub repository pratyushwinorlearn/learning-management-system, generated by GitDiagram from its file tree, README and a sample of source files (last updated 2026-09-26). It is an AI-made overview: check details against the source.

## Overview

The tree identifies a Spring-based user-registration and exam application, with separate admin and student areas and modules for exams, questions, answer sheets, results, and learning materials. The apparent user journey is registration or login, exam setup and taking, then answer and result handling. The README is empty and no source excerpts were provided, so component interactions, persistence details, and external integrations cannot be verified; the graph therefore groups the evidenced modules without asserting call or data-flow edges.
