Many students have the same or similar high school grades so how do universities choose between the hundreds of people who apply to their courses when they have not met any of these people? The personal statement helps with this process. What is a personal statement? A personal statement is basically information about you but it helps admissions staff decide if they want to offer you a place on a specific course at their university. All universities have a certain image and they are looking for more than just your grades at high school; they want to know if your personality, attitude and life experience will "fit" with their university. Think of it like a job application. When you apply for a job you have to write a personal statement which tries to persuade the company that you are the best person for the job. In the same way the personal statement aims to persuade universities that you are the kind of student they want.
When you are trying to get into a university, a grad school, or even a specialty school, more times than not a personal statement is required. The first thing that you need to do before you begin to write your personal statement is to write down all of your thoughts. After that is done you can begin to edit your work. You may want to believe that your first thoughts are gold, but in order to write a successful personal statement you must edit it often.
