1. Understanding the US Admissions Holistic Review | 理解美国大学整体性评估

US colleges evaluate applicants holistically, meaning they look beyond grades and test scores. Your academic record, standardized tests, essays, recommendation letters, extracurricular activities, and demonstrated interest all contribute to a single narrative.

美国大学采用整体性评估，不仅看分数。成绩单、标化考试、文书、推荐信、课外活动以及“表现出的兴趣”共同构成你的申请形象。招生官希望看到一个有深度、有热情、能贡献社区的完整的人。

Academic Rigor – Course difficulty and GPA trend matter as much as absolute grades. 学术严谨度 – 课程难度和GPA趋势与绝对分数同等重要。
Test Scores – SAT or ACT scores (if submitted) supplement academic evidence; many schools have adopted test‑optional policies. 标化成绩 – SAT或ACT成绩（如递交）补充学术证明；许多学校已实施标化可选政策。
Extracurriculars – Depth and leadership in a few activities outweigh scattered participation. 课外活动 – 少数活动的深度和领导力远胜于泛泛参与。
