A while ago, I was asked to take a critical look at a personal statement, which spanned the student's life from age two to eighteen. The personal statement made gripping reading but was far too long and the student had not been selective enough in the abundance of material she choose from. The word count ran to 1귔 words _ far too long for a personal statement. The task of reducing your personal statement can be enthusiastically undertaken, but the problem is that you need to look at your original brainstormed ideas to organise your material for the selection process. The only criterion you need to apply at this stage is this incident of sufficient interest to the admission officer.
Another important role of the PS is that it allows you to explain, although briefly, some information that may not be accurately represented by your transcript or Curriculum Vitae. For example, your GPA might be low because your school places a cap on grades given to students belonging to your major. Another example would be explaining the connection between your undergraduate major and your chosen graduate major, which might seem incongruous at first inspection. For these reasons alone, it is extremely important that you follow a guideline in composing your own PS.
