When applying to any school, whether it’s undergraduate or graduate, you will always be required to submit one or more written documents. The purpose of these documents is to allow the admissions committee to find out more about the students on a personal level. Looking at your test scores, credentials, class rank, and similar data is not enough. There are thousands of students applying from all over the world with similar application to yours. Therefore, your writing is arguably more important than anything else you submit, as it gives you the chance to express what makes you stand out from the rest of the applicants.
