Moving from Year 10 into the final GCSE year is a pivotal moment in your computer science journey. This guide helps you consolidate what you have learned, bridge any gaps, and prepare confidently for Year 11 and beyond, including A-Level study.
从10年级升入GCSE最后一年是计算机科学学习的关键时刻。本指南帮助你巩固所学、弥补差距，并为11年级及之后的学习（包括A-Level）做好充分准备。
1. WJEC GCSE Computer Science Overview | WJEC GCSE计算机科学概览
The WJEC GCSE Computer Science specification is structured into three components: a theory exam, an on-screen programming exam, and a non-exam assessment (NEA) software development project.
WJEC GCSE计算机科学规范分为三个部分：理论考试、上机编程考试和非考试评估（NEA）软件开发项目。
Component 1 (50%) tests understanding of computer systems, data representation, networks, cybersecurity, and ethical issues through a written paper.
组成部分1（占50%）通过笔试考查计算机系统、数据表示、网络、网络安全和伦理问题的理解。
Component 2 (30%) is an on-screen examination that assesses computational thinking, programming, and algorithm design, typically using Python.
组成部分2（占30%）为上机考试，评估计算思维、编程和算法设计，通常使用Python语言。
Component 3 (20%) involves a practical programming project where you design, develop, and evaluate a solution to a real-world problem.
组成部分3（占20%）是一个实践编程项目，你需要为实际问题设计、开发并评估一个解决方案。
2. Securing Your Year 10 Foundations | 巩固10年级基础
Year 10 usually covers the core theoretical topics from Component 1 and the introductory programming concepts needed for Components 2 and 3.
10年级通常涵盖组成部分1的核心理论主题，以及组成部分2和3所需的编程入门概念。
Make sure you are completely comfortable with binary, hexadecimal, and denary conversions; logic gates; and the fetch-decode-execute cycle.

If any of these fundamentals feel shaky, use flashcards, online quizzes, and past-paper questions to build fluency before Year 11.
如果这些基础知识还有薄弱之处，利用闪卡、在线测验和历年真题来强化，为11年级做好准备。
3. Developing Computational Thinking Skills | 培养计算思维能力
Computational thinking is the backbone of the course and involves decomposition, pattern recognition, abstraction, and algorithm design.
计算思维是本课程的核心，包括分解、模式识别、抽象和算法设计。
Decomposition means breaking a complex problem into smaller, manageable parts; practise this by planning any programming task on paper first.
分解指将复杂问题拆分为更小、可管理的部分；你可以通过先在纸上规划编程任务来练习这一方法。
Abstraction involves filtering out unnecessary detail to focus on what is important—essential when modelling complex systems.
抽象涉及过滤掉不必要的细节，专注于重要部分——这在建模复杂系统时至关重要。
Use pattern recognition to spot similarities between problems, so you can apply known solutions to new challenges efficiently.
