For undergraduate admissions, A-Level requirements at top universities typically range from A*AA to AAA, with an A* in Mathematics often mandatory for Computer Science. The IB equivalent usually requires a total of 39-42 points with 7 in HL Mathematics: Analysis and Approaches. Strong performance in subjects like Further Mathematics, Physics, or Computer Science itself strengthens the application, though not always required. For US colleges, a rigorous high school curriculum including calculus, statistics, and any programming electives matters greatly.
本科申请方面，顶尖大学的A-Level要求通常为A*AA至AAA，数学常须达到A*。IB总分一般需39-42分，且高级数学：分析与方法须获7分。进阶数学、物理或计算机科学等科目的优异成绩能增强申请竞争力，尽管并非所有院校强制要求。对于美国大学，修读包含微积分、统计学和编程选修课的严格高中课程尤为重要。
For Master’s programmes, a Bachelor’s degree in CS or a closely related field with a solid GPA (often a 2:1 or 3.0/4.0 minimum) is expected. Some conversion courses accept non-CS backgrounds but demand evidence of quantitative aptitude.
硕士项目则期待申请者拥有计算机科学或密切相关领域的学士学位，且GPA优良（通常最低2:1或3.0/4.0）。部分转换课程接受非CS背景，但要求证明具备定量分析能力。
5. Standardized Tests and Language Proficiency | 标化考试与语言能力
US-bound undergraduate applicants often need the SAT or ACT (though many schools remain test-optional). A competitive SAT score is 1500+, with 780+ in Math. The GRE is sometimes required for US Master’s programmes, with top candidates scoring 165+ in Quantitative. However, many UK, Canadian, and Australian universities waive the GRE, placing greater weight on academic transcripts.
赴美本科申请者常需SAT或ACT成绩（尽管许多学校仍实行可选政策）。有竞争力的SAT分数为1500分以上，数学780分以上。美国硕士项目有时要求GRE，顶尖申请者的数学成绩通常在165分以上。然而，许多英国、加拿大和澳大利亚大学豁免GRE，更看重学术成绩单。
For non-native English speakers, IELTS 6.5-7.0 or TOEFL iBT 90-100 is the standard baseline. Top-tier CS programmes like Stanford or Cambridge typically require IELTS 7.5 or TOEFL 110. Prepare these exams early, leaving time for retakes if needed.
对于非英语母语者，雅思6.5-7.0或托福90-100是标准基准。斯坦福或剑桥等顶级CS项目通常要求雅思7.5或托福110。尽早准备这些考试，留出重考时间。
6. Building a Strong Profile | 打造强有力的背景
Grades alone rarely secure admission to elite CS programmes. You must demonstrate genuine passion through projects: a GitHub repository showcasing a mobile app, a machine learning model, or contributions to open-source software speaks louder than a personal statement claiming you “love coding.” Competitions such as the USA Computing Olympiad, British Informatics Olympiad, or Google Code Jam add concrete evidence of problem-solving skill.
仅靠成绩很难被精英CS项目录取。你必须通过项目展现真正的热情：一个展示移动应用、机器学习模型或开源贡献的GitHub仓库，比个人陈述中声称你“热爱编程”更有说服力。美国计算机奥林匹克、英国信息学奥林匹克或谷歌编程挑战赛等竞赛为目标明确的问题解决能力提供了具体佐证。
Research experience, even a summer project with a local university professor, can distinguish an applicant. Internships at tech firms — even at startups — show you understand how CS is applied in real-world environments. All these activities should converge into a coherent narrative about your interests within CS.
研究经历，哪怕是暑期跟随本地大学教授完成的一个项目，都能让申请者脱颖而出。在科技公司——哪怕是初创公司——的实习经历，表明你了解计算机科学如何应用于真实环境。所有这些活动都应汇聚成一个关于你在CS领域兴趣的连贯叙事。
7. Crafting Your Personal Statement | 撰写个人陈述
A compelling personal statement for CS avoids cliches such as “I have been passionate about computers since I was a child.” Instead, anchor your narrative in a specific problem you solved or a project you built. Describe the technical choices you made, obstacles you encountered, and what you learned — this reveals your thinking process. For US Common App essays, show personal growth through a non-academic lens, but let your supplemental essays delve into CS specifics.
一篇有说服力的计算机科学个人陈述应避免“我从小就热爱计算机”这类陈词滥调。相反，要将叙述锚定在你解决的一个具体问题或你构建的一个项目上。描述你做出的技术选择、遇到的障碍和学到的经验——这能揭示你的思维过程。对于美国通用申请文书，通过非学术视角展现个人成长，但让补充文书深入探讨CS相关细节。
For research-oriented programmes, mention a paper or concept that captivated you and connect it to the faculty’s expertise. Tailor each statement to the institution, demonstrating you have explored their labs, modules, and unique opportunities such as hackathons or industry placements.
对于研究型项目，可提及一篇令你着迷的论文或概念，并将其与院系教授的专业领域联系起来。每份陈述都应针对具体院校定制，表明你已经了解其实验室、课程模块以及独特的黑客马拉松或行业实习机会。
8. Securing Strong Recommendations | 获得有力推荐信
Choose recommenders who know your quantitative and analytical abilities intimately — typically a Mathematics or Computer Science teacher, and perhaps a Physics teacher. Provide them with a “brag sheet” listing your grades, projects, competition results, and specific examples of your dedication (like when you debugged code for three extra hours). This enables them to write detailed, anecdote-rich letters rather than generic praise.
选择那些深入了解你定量和分析能力的推荐人——通常是数学或计算机科学老师，或许还有物理老师。向他们提供一份“亮点清单”，列出你的成绩、项目、竞赛成果以及体现你专注投入的具体事例（比如额外花费三小时调试代码）。这能帮助他们写出细节详实、充满轶事的推荐信，而非泛泛的赞美。
Secure recommendations well before deadlines, ideally a month in advance. For US applications, be aware that counselors and teachers may handle dozens of requests; respectful, early communication goes a long way. After admission, thank them; sustained relationships matter in academia.
在截止日期前尽早落实推荐信，最好提前一个月。对于美国申请，需注意辅导员和老师可能要处理数十封请求；尊重对方、提早沟通会大有帮助。录取后要向他们致谢；在学术界，长期维持的关系很重要。
9. Interview Preparation | 面试准备
Some universities, particularly Oxford, Cambridge, and Imperial, conduct technical interviews where you solve problems on a whiteboard or shared screen. Practice solving algorithm puzzles, explaining your reasoning aloud as you go. Interviewers care less about a perfect answer and more about your approach, adaptability, and response to hints. Platforms like Pramp or LeetCode mock interviews can sharpen these skills.
一些大学，尤其是牛津、剑桥和帝国理工，会进行技术面试，要求你在白板或共享屏幕上解题。练习解答算法难题，并边做边大声解释推理过程。面试官不太关心完美答案，更看重你的方法、适应性以及对提示的反应。使用Pramp或LeetCode模拟面试平台可以磨炼这些技能。
For US universities, alumni or admissions interviews are often conversational. Be prepared to discuss your projects, why you want to study CS, and how you would contribute to the campus community. Have thoughtful questions ready about the programme to demonstrate engagement.
对于美国大学，校友或招生面试通常是交谈式的。准备好讨论你的项目、为何想学计算机科学，以及你将如何为校园社区做出贡献。并准备一些关于该专业的有深度问题，以展现你的投入度。
