Another important role of the PS is that it allows you to explain, although briefly, some information that may not be accurately represented by your transcript or Curriculum Vitae. For example, your GPA might be low because your school places a cap on grades given to students belonging to your major. Another example would be explaining the connection between your undergraduate major and your chosen graduate major, which might seem incongruous at first inspection. For these reasons alone, it is extremely important that you follow a guideline in composing your own PS.
Meanwhile, not a few schools require a third type of application document, which is the Question and Answer (Q and A) essay. Although this may take the form of a quasi_PS, the questions require that you answer them in a specific manner. This essay usually ranges from 300 to 600 words, thereby limiting the amount of information that should be included. Nevertheless, Q and A essays belong to an entirely different category and will not be explained here. Instead, in the following useful guide, we will explain everything you need to know in creating your own PS and offer useful suggestions to help you polish your essay further.
