9. Personal Statement Structure | 个人陈述结构
A strong personal statement for STEM follows this simple architecture: 80% academic exploration, 20% personal qualities. Begin with a specific moment that sparked your interest — a problem you encountered, a book you read, or a project you attempted. Avoid clichéd openings like "I have been passionate about computers since childhood".
一份出色的 STEM 个人陈述遵循简单结构：80% 学术探索，20% 个人品质。以一个激发你兴趣的具体瞬间开篇——一个你遇到的问题、读过的一本书，或尝试过的项目。避免陈词滥调，如 "我从小就对计算机充满热情"。
Then discuss two or three super-curricular activities in depth. For each, explain what you did, what you learned, and what new questions it raised. Connect these to specific modules on the course you are applying for. End with a short paragraph on skills like resilience or teamwork, evidenced by a non-academic activity.
然后深入讨论两到三项超纲活动。每项都要说明你做了什么、学到了什么、以及由此产生了哪些新问题。将这些与所申请课程的具体模块联系起来。最后用一小段陈述抗逆力或团队合作等技能，并以非学术活动作为例证。
10. Admissions Tests (TMUA, MAT, PAT, etc.) | 入学考试 (TMUA, MAT, PAT 等)
| Test | Relevant Majors | Key Preparation |
|---|---|---|
| MAT (Mathematics Admissions Test) | Computer Science, Mathematics | Focus on logic, algorithmic reasoning, and problem-solving under time pressure. |
| TMUA (Test of Mathematics for University Admission) | Computer Science, Data Science, Economics | Practice mathematical reasoning and prove/disprove type questions. |
| PAT (Physics Aptitude Test) | Mechanical Engineering, Physics | Revise mechanics, waves, and electricity; practise multi-step physics problems. |

11. Interview Preparation Tips | 面试准备技巧
STEM interviews often begin with a problem based on your personal statement or a pre-released reading. For Computer Science, you might be asked to trace through a sorting algorithm on a whiteboard. For Mechanical Engineering, expect a question like "Sketch the stress distribution in a cantilever beam under load." Data Science candidates could be asked to interpret a statistical graph and critique its design.
STEM 面试通常以基于个人陈述或预发材料的问题开场。计算机科学面试中，你可能需要在白板上逐步推演一个排序算法。机械工程可能遇到这样的问题："画出悬臂梁在载荷下的应力分布。" 数据科学申请者可能被要求解读统计图表并评判其设计。
Think aloud. Articulate every assumption and why you are making it. If you get stuck, ask for a hint rather than staying silent. Demonstrating teachability is often more important than reaching the right answer immediately.
边思考边说出来。阐明每个假设及其原因。如果被卡住，主动寻求提示，而不是保持沉默。展示出可教性往往比立刻给出正确答案更重要。
