Long before you have reached the point of revision, however, it is important that you personal statement is intended as a selling tool for you to gain entry to your chosen university. If you wish to interest the reader it is important that you are your own critic. You will need to prune and polish, check grammar and spelling, take another look at your style: in fact, you may need to re_write your first few sentences to ensure your personal statement is powerful and will capture your readers attention instantly. A great way to help with this is to read sample personal statements these samples will give you a clear idea of how you may improve your opening.
Then look at some resources for writing personal statements and get some advice. There are lots of websites which will offer you advice for writing a personal statement but it is best to look at websites from reputable organisations such as UCAS or student advice websites which are well used such as The Student Room. Remember to ask your teachers, friends and family for advice. A good question to ask them is "what do you think makes me different from other people? or "how would you describe me?" because the answers often give you some interesting information that you hadn't thought about. The personal statement is not something you can write quickly so be prepared to think a lot about yourself, your qualities, skills, experience, likes and dislikes. You are unlikely to meet the people who read it so your personality needs to come though on paper; this is difficult.
