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.
Proofread _ As with all of the application, it's crucial that you edit your personal statement. This little piece of writing reflects on you; don't let it scream "sloppy"! Write your statement and then proofread it for typos and grammar. The next day, read it again. Ask a good friend or teacher to read it too. Make your statement as near perfect as possible and it will serve your app well. A good personal statement could be the deciding factor for an applicant that is not clearly in or out. Take the time to make your writing work to your advantage and let your voice be heard in your application!
