请注意，每所学校的具体要求可能略有不同。务必在每所大学的招生官网上核实准确的资料清单和截止日期。建议从 10 年级就开始整理这些材料，以免到最后一刻手忙脚乱。
2. 9th–10th Grades: Laying the Groundwork | 9–10 年级：夯实基础
The early years of high school are not directly filled with application forms, but they set the stage for everything that follows. Focus on taking a challenging curriculum in English, math, science, and social studies. Establish strong study habits that lead to consistent grades in the A / A* range. Admissions officers will see your entire high school record, so an upward trend starting in Grade 9 is powerful. Also begin exploring extracurricular activities: join a club, learn an instrument, play a sport, or volunteer in your community. Depth of commitment starts with early exposure.
高中的前两年并不会直接面对申请表格，但它们是整个申请之路的基石。重点在于选择具有挑战性的课程——英语、数学、科学和社会科学都要打好基础。养成扎实的学习习惯，争取保持 A 或 A* 等级的成绩。招生官会审阅全部高中成绩单，因此从 9 年级就呈现出上升势头将非常有利。同时，开始探索课外活动：加入一个社团、学习一门乐器、参与一项运动或在社区做志愿者。长期的投入与深度，都始于早期的尝试。
3. 11th Grade Fall: Standardized Testing & Course Rigor | 11 年级秋季：标化考试与课程难度
Fall of junior year is the ideal window for your first SAT or ACT attempt. Register for the October or November test date and prepare systematically using official practice questions. At the same time, continue to take the most advanced courses available to you, such as AP, IB, or A-Level subjects. Course rigor is one of the top factors in admission decisions, so you need to demonstrate intellectual curiosity and the ability to handle college-level work. Meet with your school counselor to map out senior-year courses and discuss preliminary college interests.
11 年级秋季是参加首次 SAT 或 ACT 考试的最佳时机。报名 10 月或 11 月的考试，并利用官方练习题系统备考。同时，继续修读所在学校提供的最具挑战性的课程，例如 AP、IB 或 A-Level 科目。课程难度是录取决策中最重要的考量因素之一，你需要展现出求知欲以及应对大学水平课业的能力。此时还应约见学校的升学指导，规划 12 年级的选课并初步探讨大学申请意向。
4. 11th Grade Spring: Extracurricular Depth & College Research | 11 年级春季：课外活动深度与择校调研
As you move through the second semester of Grade 11, intensify your involvement in two or three key activities. Rather than collecting dozens of superficial memberships, aim for leadership roles, significant projects, or impactful contributions. This is also the time to build a preliminary college list of 15–20 schools that fit your academic profile, financial needs, and personal preferences. Attend virtual or in-person information sessions, start reading student reviews, and create a spreadsheet that tracks application deadlines, essay requirements, and testing policies.
在 11 年级下学期，你要在 2–3 项核心活动中投入更多精力。与其收集几十个浅尝辄止的社团经历，不如争取领导职位、策划重要项目或做出有影响力的贡献。此时还应建立一份包含 15–20 所大学的初步选校清单，筛选标准需兼顾学术水平、经济需求和你的个人偏好。参加线上或线下的招生宣讲会，浏览在校生评价，并用电子表格整理各校的申请截止日期、文书要求和标化考试政策。
5. Summer Before Senior Year: Essays & Activity List Drafting | 12 年级前暑假：文书与活动列表草稿
The summer after Grade 11 is the most productive block of time you will have. Use it to draft your Common App personal essay, aiming for an authentic story that reveals something deeper than your resume. Simultaneously, complete a first version of your activities list, describing each entry with precise action verbs and quantitative impact. If you still need to improve test scores, this is your chance for a final summer sitting of the SAT or ACT. By the end of August, you should have at least three polished essay drafts and a finalized testing plan.
11 年级结束后的暑假是你能集中利用的最宝贵时间。用它来起草 Common App 主文书，力求写出一篇比简历更深刻的、展现真实自我的故事。同时，制作活动列表的初稿，用精准的行为动词和量化成果来描述每一项经历。如果你仍需提高标化考试成绩，这也是参加最后一次暑期 SAT 或 ACT 的机会。到 8 月底，你应该至少完成三稿修改过的主文书，并最终确定考试计划。
6. August–September: Finalizing School List & Creating Accounts | 8–9 月：确定选校清单与创建申请账户
At the start of senior year, narrow your college list to a balanced mix of 6–12 schools, including safety, target, and reach options. Create accounts on the Common App or Coalition App, fill in your demographic and educational information, and add all your colleges. For each school, review the supplement tab carefully: note deadlines, required subject tests, and any additional materials such as portfolios. Request your official transcript from the counseling office and check if your school uses a platform like Naviance or Scoir for document submission.
12 年级开学之初，将选校清单精简至 6–12 所结构合理的学校，包含保底、匹配和冲刺院校。在 Common App 或 Coalition App 上注册账户，填写个人信息与教育背景，并将所有目标学校加入申请列表。逐一查看每所学校的补充材料栏，记录截止日期、是否要求学科考试以及是否需要提交作品集等额外材料。向学校升学办公室申请正式成绩单，并确认你的学校是否通过 Naviance 或 Scoir 等平台提交文件。
7. September–October: Teacher Recommendations & Transcripts | 9–10 月：教师推荐信与成绩单
Approach two teachers who taught you in academic subjects during junior year or the start of senior year. Ask them politely and in person, providing a summary sheet that highlights your achievements, interests, and college goals, along with the deadlines. Confirm that your counselor will submit the counselor recommendation and school profile. If you are applying for financial aid, begin filling out the CSS Profile or the International Student Financial Aid Application, as some early deadlines fall in November. Verify that your transcript has been uploaded and shows all completed coursework accurately.
联系两位在 11 年级或 12 年级初教过你学术科目的老师。当面提出请求，并提供一份简明摘要页，列出你的成就、兴趣和选校目标，同时明确推荐信截止日期。确认升学指导将会提交指导老师推荐信和学校简介。如果你申请助学金，现在开始填写 CSS Profile 或国际学生助学金申请表，因为部分早申请的助学金截止日期就在 11 月。最后，核对自己的成绩单是否已成功上传，并且准确反映了所有已完成的课程。
8. October–November: Early Decision / Early Action Submissions | 10–11 月：早决定/早行动提交
Many selective colleges offer Early Decision (binding) or Early Action (non-binding) plans with deadlines around November 1 or November 15. If you are applying early, finalize your Common App essay, supplement essays, and activities list well ahead of the deadline. Request that your standardized test scores be sent officially from the testing agency. Double-check that all recommendation letters and transcripts have arrived. Submit your application at least 48 hours before the deadline to avoid technical issues. After submission, regularly monitor your applicant portal for any missing items.
许多精英大学提供早决定（绑定）或早行动（非绑定）申请计划，截止日期通常在 11 月 1 日或 11 月 15 日前后。如果你选择早申请，务必在截止日期前彻底定稿 Common App 主文书、附加文书和活动列表。要求考试机构官方寄送你的标化成绩。再次确认所有推荐信和成绩单都已到达。在截止日期前至少 48 小时提交申请，以防出现技术故障。提交之后，定期查看申请门户，确认是否还有缺漏材料。
9. November–December: Regular Decision Supplements & Final Tests | 11–12 月：常规申请补充文书与最后考试
After the early round, shift your attention to Regular Decision applications, which are typically due between January 1 and January 15. Write your remaining supplement essays with the same care you gave to early applications, researching each campus culture thoroughly. If you plan to take a final SAT or ACT in December, register early; those scores will still reach most colleges in time. Continue working closely with your counselor to submit mid-year grades, which become a critical part of the academic review once they are available.
早申请阶段结束后，立刻将重心转向常规申请（Regular Decision），截止日期一般集中在 1 月 1 日至 1 月 15 日。用对待早申请同样的心力完成剩余学校的补充文书，深入研究每所学校的校园文化。如果你计划在 12 月参加最后一次 SAT 或 ACT，务必尽早报名；这些成绩通常仍能及时送达多数大学。继续与升学指导密切配合，提交期中成绩单，这将是录取委员会审核你后续学术表现的重要依据。
10. January–February: Interviews & Updated Grades | 1–2 月：面试与期中成绩更新
Some universities offer optional or alumni interviews during January and February. If you are invited, treat the interview as a two-way conversation—prepare thoughtful questions and practice articulating your interests. Update your college list with any new achievements, such as competition awards, research projects, or leadership developments. If you have been deferred from an early application, write a polite, concise letter of continued interest to that admissions office, including meaningful updates and reaffirming your commitment to attend if admitted.
部分大学在 1 月和 2 月会安排可选面试或校友面试。若收到邀请，请将面试视为双向交流的机会——提前准备有深度的问题，并练习清晰表达自己的兴趣。将任何新的成就（如竞赛获奖、研究项目或领导力进展）更新给仍在审核的学校。如果你在早申请中被延期考虑，可以向招生办写一封礼貌且简短的“持续兴趣信”，附上有价值的更新，并重申你一旦被录取便会入学的意愿。
11. March–April: Decisions, Financial Aid Offers & Waitlists | 3–4 月：录取结果、助学金与候补名单
Regular Decision notifications are released between mid-March and early April. You may receive offers of admission, denials, or waitlist invitations. Carefully compare financial aid packages, using the net price calculator on each college's website to understand the actual cost. If waitlisted, follow the college's instructions—some allow you to accept a waitlist spot and submit additional materials. Plan visits (or virtual revisit experiences) to your top-choice campuses to assess the environment before making a final choice.
常规申请的结果在 3 月中旬至 4 月初陆续公布。你可能会收到录取、拒绝或候补通知。仔细比较每所学校的助学金方案，利用大学官网上的净价计算器了解真实费用。如果被列入候补名单，按照学校的要求操作——有些允许你接受候补名额并补充提交材料。通过实地访校或虚拟重访，深入了解你最青睐的校园环境，为最终决策做好准备。
12. May 1: Decision Day & Preparing for Enrollment | 5 月 1 日：决策日与入学准备
May 1 is the universal National College Decision Day in the United States. By this date, you must choose one institution and submit the enrollment deposit. After confirming your spot, complete the housing application, sign up for orientation, and satisfy any health or immunization requirements. International students should begin the I-20 request process and book visa appointments promptly. Celebrate your accomplishment and start planning for the exciting transition ahead.
5 月 1 日是美国全国统一的大学选择日。在此之前，你必须确定就读一所学校并缴纳入学押金。确认名额后，随即完成住宿申请、注册新生指导活动，并满足健康与疫苗要求。国际学生应立即开始申请 I-20 表格，并尽快预约签证面签。庆祝你所取得的成就，并开始规划即将到来的精彩旅程。
