PS is a personal statement (also called a letter of recommendation). The function of writing PS is to help schools further understand whether students are suitable for their own schools or their own majors. Foreign universities choose students mainly based on two considerations: academic performance and personal ability. Academic achievement is a series of transcripts in the form of data submitted by students when they apply for schools, while personal ability is mainly reflected by PS and reference. If the transcript is a written test, then PS is an interview, and the combination of the two can cross the threshold of a prestigious school. At present, all universities in British and American ports and some universities in Canada need to submit PS when applying. Second, what is the soul of PS? This question must be written in the front, because only by clarifying this question can you stand higher and see farther than others when preparing all the application documents. PS that can impress people have one thing in common, that is, they have souls! This soul lies not in gorgeous language, strange experience, or the accumulation of ranking awards, but in your love and understanding of the application field! For example, a PS of applied mathematics describes his experience of participating in one mathematical modeling contest after another. The language is very simple, and it doesn't say what my GPA is. I ranked first, but it was very touching, because it really reflected his love for mathematical modeling. I think he writes very well. In fact, other application materials, transcripts and resumes are rational. What, how many points are clear, PS is the only thing that can express feelings and touch people's hearts. I think this is the unique meaning of PS.
