When you are sifting through the vast amount of sample you will have access to, be sure that you are looking for samples that will pertain to you and your personal situation. Once you find sample personal statements that you think have helpful information you can print them out and highlight any areas that you feel may help you when you set out to write your own statement. It is also a good idea to take notes as you go along.
You already know that your personal statement could be the one factor that keeps you out, or lets you into the school of your dreams, but you may not know how important it is to have a fresh set of eyes on it before you turn it in. While you may have read over your personal statement several times, there are still reasons that you will want someone else to read it over as well.
