OK, I've done some research and lots of thinking, now what? Write down some ideas and topics that you think are relevant and then expand them into sentences and paragraphs. Next show your personal statement to as many people as possible to get feedback and advice and draft it again and again until you are happy with it. Always read it with a critical eye and imagine you are the admissions officer for your chosen course and ask this question: Would you give you a place on this course after reading your personal statement and WHY? _ What should I focus on if I'm an EU or International student and English is not my first language?
It is important to cover whatever period you intend to include in your personal statement because time spent planning your sequence and the method you feel happiest with will undoubtedly make the actual writing that much easier for you.
