美国普渡大学毕业证 成绩单：国际学生申请指南
美国普渡大学是世界顶尖的公立研究型大学，其西拉法叶主校区素有“宇航员的摇篮”的美誉。作为“公立常春藤”成员，普渡大学以其顶尖的工程学、农业科学等学科实力，吸引了超过9,000名来自全球127个国家的国际学生。对于有志于此的中国留学生而言，申请过程需要从学术、语言到资金进行全面且细致的准备。
一、本科申请：扎实的学术与高标准的英语能力
本科申请要求严格。学术上，学校期望申请者拥有优异的高中成绩，建议高中总平均绩点（GPA）达到3.5（4.0分制）及以上；若申请工程学院等热门专业，建议GPA达到3.7或更高。虽然SAT或ACT考试成绩为可选提交，但优异的成绩是重要加分项。在语言能力上，直接录取要求托福网考（iBT）79分或雅思6.5分是基础门槛。值得注意的是，工程学院、理学院等热门学院要求更高，通常要求托福88分或雅思7.0分。
二、研究生申请：专业背景与科研潜力的双重证明
研究生申请要求更为专业和具体。申请者须持有经认证的学士学位，本科阶段GPA通常需达到3.0以上，但多数研究生课程会期望更高的平均成绩。理工科专业普遍要求或建议提交GRE成绩（如工程类要求315分以上），而商科则多需GMAT成绩（建议650分以上）。语言要求同样严格，研究生项目普遍要求托福总分80-100分或雅思6.5-7.5分，具体分数因专业而异。申请热门专业（如计算机科学、工程学院项目）通常要求更高，例如托福100分。
三、核心申请材料：构筑全面个人画像
一份有竞争力的申请，离不开精心准备的文书材料。本科申请者必须通过Common Application系统在线提交申请，并支付申请费。核心材料包括经认证的中英文高中成绩单与毕业证明、1-2封教师推荐信、个人陈述（阐述学术兴趣与经历）等。研究生申请则通常需要2-3封推荐信、一份详细的研究或学习目的陈述，以及个人简历。部分专业（如英语文学博士）对写作样本有严格篇幅（10-15页）和形式要求。
四、财务规划、签证与关键时间
财务规划是申请的关键环节。国际本科生每年的总花费（含学费、住宿与生活费）估计约为53，000至57，000美元。研究生费用因学院而异，如工程学院年学费约为35,000-40,000美元。被录取后，国际学生必须按要求提供充足的资金证明，以获得申请F-1学生签证所必需的I-20表格。申请者必须密切关注截止日期，本科秋季入学的优先申请截止日期通常为1月1日。
Part 1: Undergraduate and Graduate Academic Requirements
Applying to Purdue University as an international student begins with meeting high academic standards. For undergraduate admission, a strong high school record is essential, with a recommended overall GPA of 3.5/4.0 or higher; competitive programs like engineering suggest a GPA of 3.7+. Submission of SAT or ACT scores is optional but can enhance an application. Proof of English proficiency is mandatory, with typical minimums of TOEFL iBT 79 or IELTS 6.5; the College of Engineering and other selective schools often require higher scores, such as TOEFL 88 or IELTS 7.0.
For graduate programs, applicants must hold a bachelor's degree, and many programs set a minimum undergraduate GPA of 3.0, with competitive averages being significantly higher. Most programs require standardized tests like the GRE (e.g., 315+ for engineering) or GMAT (650+ for business). Language requirements are also rigorous, generally ranging from TOEFL 80-100 or IELTS 6.5-7.5, with higher demands for top-ranked programs.
Part 2: Application Components and Key Logistics
A compelling application requires a complete portfolio of materials. Undergraduate applicants must apply online via the Common Application. Essential documents include official academic transcripts, letters of recommendation (typically 1-2), and a personal statement outlining academic interests. Graduate applications usually require 2-3 recommendation letters, a detailed statement of purpose, a resume, and, for some programs (e.g., English), a substantial writing sample (10-15 pages).
Financial planning is crucial. The estimated annual cost for international undergraduates is approximately $53,000 to $57,000. After admission, students must provide documented proof of financial support to receive the I-20 form for the F-1 student visa. Adherence to deadlines is vital; the priority application deadline for fall undergraduate admission is typically January 1.
