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.
But you've got to sound: Like you care a lot, and like you're completely devoted to it. An example: "I am completely devoted to medicine for the rest of my life. It's everything for me because it's the only thing that's going to allow me to express who I am personally and professionally." High_impact language has this very strong absolute, emotionally rich, concrete side to it where as a reader I am completely engrossed, engaged, enmeshed. I buy it. I believe you. Some of the best places to look for this kind of writing is where there is someone who is making a very impassioned speech. One of the best places that I know is in the most powerful, compelling, moving speeches of our time. Like Martin Luther King's "I Have A Dream," or speeches by Gandhi, or speeches by John F. Kennedy, or speeches by Barack Obama. Speeches that really elevate you and make you feel that there's hope for you, hope for us and that there's something bigger to strive for.
