## Overview

This repository is a collection of NWPU Software School study materials, not a software application. The principal workflow is to find materials by course and year, then read or use the relevant notes, examples, and exercises. The tree shows selected resources across A/B/C courses; the README describes a broader collection. Relationships below represent access to materials, not runtime calls. The graph is limited to course areas evidenced by the supplied tree.
