The Difference between Professional Schools (Law,     Busines，Medical) and Graduate Schools:
While graduate school committees certainly expect well-written, thoughtful essays, they are looking for different content from their applicants. For graduate schools, that will likely be funding your education for the next 2-6 years, they want to know about your specific qualifications in your field. In other words, you should spend most of your essay explaining your interest, research experience, and disciplinary goals. Be sure that you research the school well to determine whether your interests align with those of a faculty member. Not only must you convince a committee that you are a qualified applicant, but you must also convince them (and probably also a particular professor) that your interests match the needs of the department; after all, they are about to invest a substantial amount of money and time in your education. With this in mind, limit the personal anecdotes and extracurricular interests to those that pertain directly to your field of interest or career goals.

    法/商/医学院与研究生院对PS的要求区别如下:
    研究生院的录取委员会期待着看到有文采有思想的文章, 但同时他们在申请者身上寻找一些与众不同的东西. 对于研究生院而言, 他们将要在接下来的2至6年中资助您的学术生涯, 因此他们想了解您在您的研究领域中具体有什么过人之处. 换句话说, 您应该使用较大的篇幅阐述您的兴趣、研究经验、以及一直追求的目标. 一定要认真地调查以确保您的研究迎合了教授的兴趣. 您不仅要说服录取委员会相信您是一个合格的申请者, 而且您要说服他们(也许是其中某一个教授)相信您的研究兴趣符合系里的需要; 毕竟, 他们将要在您身上投资一大笔资金和大量的时间. 考虑到这些, 您应该少说一些您的生活经历和业余兴趣什么的, 多讲讲您感兴趣研究领域和职业目标等.
