## Overview

This repository is a personal archive of Beijing Institute of Technology computer-science course materials, not an executable product. The principal workflow is a student browsing the semester/course collections, opening relevant notes, assignments, exams, code, or project files, and using them for study. The README documents the main subject categories; the tree shows their varied contents. Relationships below describe documented organization and access only, not an application pipeline. Individual files are grouped into course collections because no runtime orchestration is present.

Main entry points: [`1semester 大一上`](https://github.com/yyt-0901/cs-bit-information/tree/master/1semester%20%E5%A4%A7%E4%B8%80%E4%B8%8A) (Year-one materials), [`README.md`](https://github.com/yyt-0901/cs-bit-information/blob/master/README.md) (Study archive), [`2semester 大一下`](https://github.com/yyt-0901/cs-bit-information/tree/master/2semester%20%E5%A4%A7%E4%B8%80%E4%B8%8B) (Spring materials), [`3semester 大二上`](https://github.com/yyt-0901/cs-bit-information/tree/master/3semester%20%E5%A4%A7%E4%BA%8C%E4%B8%8A) (Year-two materials)
