The Personal statement or Essay is an essential part of your application. Its importance grows with the popularity of the course/university you are applying for. Admission tutors for competitive courses rely a great deal on this part in making their decision. Faced with a large number of applications, they can only start to distinguish between applicants based on what they say about themselves in this document. It is therefore an important piece of work that you need to give most attention to ensure that it is done well and best you can.
