So how do I know what universities want? Start by reading about the university, the course you want to study and the "entry profiles" as these will give you information about the type of student the university is looking for. Universities also want the truth so do not lie about your abilities and they want your writing so do not ask someone to write the personal statement for you. Some areas to cover include why you want to study this subject, what your future career plans are, what you do in your free time, what skills you have (academic and non_academic), what's interesting and/ or different about you.
In order for there to be tension in your personal statement, it will help to describe a highly charged incident, part of a particularly difficult period in your life. Whatever it was, you will maintain your reader's interest for that much longer. The example below shows perfect tension and suspense build up _ "When the airmail letter arrived bearing an American stamp, I knew immediately, it was from my university with my degree results, and I tore it open as excitedly as if it were a birthday present. With trembling fingers, I took out the sheets of thin blue paper _ and my heart started to pound as I began to read."
