Check for grammar, punctuation and spelling. If you're not confident about these aspects then ask someone you can trust or hire a professional to check the personal statement. _ Review your statement and ask these questions: _ Have I answered the questions required? _ Have I put forward the best examples of experiences and effects that are relevant to my field of study or who I am? _ Have I effectively answered the main question here _ Why should the Graduate School accept me over my fellow applicant? _ Does this statement reflect who I really am or do I sound like a "too good to be true" parrot? _ Would I fall asleep if I had to read this or would it grab my attention? _ Have I let my sense of humor get carried away? Do I sound too opinionated or extreme in my views? _ Have I addressed any weaknesses I have e.g. low GPA or LSAT?
It is important to cover whatever period you intend to include in your personal statement because time spent planning your sequence and the method you feel happiest with will undoubtedly make the actual writing that much easier for you.
