Things people build with this

USE CASE 1

Review past 408 exam papers with worked solutions to identify which topics are tested most frequently.

USE CASE 2

Study C++ implementations of data structures like sorting, trees, and graphs alongside exam-focused explanations.

USE CASE 3

Use concept diagrams to quickly understand how operating system memory management or network protocols work.

USE CASE 4

Identify which Chinese 985 and 211 universities accept the shared 408 exam rather than their own subject tests.

In plain English

CSPostgraduate-408 is a study resource repository for students in China preparing for the national computer science graduate entrance examination, commonly called kaoyan. In China, students who want to enter a graduate program take a standardized national exam plus subject-specific tests set by each university. For computer science, many top universities use the unified 408 exam, which covers four core subjects. The four subjects are Data Structures (how programs organize and search through information efficiently), Computer Organization (how hardware components like processors and memory work together at a low level), Operating Systems (how software manages hardware resources such as memory, storage, and running processes), and Computer Networks (how computers communicate with each other over the internet and local networks). This repository collects materials for all four subjects in one place. It includes past exam papers with worked solutions, lecture notes, concept diagrams that show how ideas connect to each other, and C++ source code for algorithm implementations. Much of the source code accompanies a course series by a prep brand known in the community as Wang Dao, which is a widely used study resource for 408 candidates. The README lists dozens of Chinese universities, grouped by whether they fall into the 985 or 211 tier. Both are government-designated rankings for highly selective research universities. This section helps prospective students identify which schools accept the shared 408 exam rather than administering their own subject tests. The repository is written entirely in Chinese and is primarily useful to students sitting the Chinese graduate admissions system.

Copy-paste prompts

Prompt 1

Using the 408 syllabus topics, explain how a B+ tree works and why databases use it for indexing, in terms a CS undergrad can understand.

Prompt 2

Write C++ code implementing a min-heap from scratch with insert and extract-min operations, as commonly tested on the 408 exam.

Prompt 3

Summarize the most frequently tested topics in the Computer Networks section of the 408 exam and which OSI layers they fall under.

Prompt 4

Explain the difference between segmentation and paging in operating system memory management as it would appear in a 408 exam question.
