先看整套文书,再决定每一篇写什么
准备补充文书时,可以先判断每一道题承担的功能:它希望补充个人背景、学术兴趣,还是社区中的经历与贡献?再选择能回应这道题的具体证据,避免多篇文章反复讲述同一段故事。以下是 Vista 的通用写作建议,具体作答范围仍以上方题组要求为准。
主文书与补充文书可以相互支持,但不必承担相同的任务。需要讨论学校匹配时,把个人经历与具体的院校机会联系起来;处理经历类题目时,重点说明自己的行动、选择与变化。最后把所有回答放在一起读,检查重复和遗漏。

先按官方前置问题选择一或两个兴趣领域,再回答理由。选择不约束录取后的专业;理由 150–200 词。
Caltech has a rigorous core curriculum and students don't declare a major until the end of their first year. However, some students arrive knowing which academic fields and areas already most excite them, or which novel fields and areas they most want to explore. If you had to choose an area of interest or two today, what would you choose? *Note that you are under no obligation to follow this choice if admitted. Why did you choose your proposed area of interest? If you selected 'other', what topics are you interested in pursuing?
