The body of your personal statement is going to be hard work _ you need to use around 50% of your word limit to give the admission representatives concrete evidence of why you stand out from the crowd in this application process. The body is also where you will be answering questions and giving examples of experience and affects of experience. Answers and evidence need to keep reflecting who YOU really are. If you're struggling to keep under the word limit, allocate each question a word limit as well.
2. Not Enough Focus On the Person _ When one studies the questions actually posed in the residency application requirement statements of most institutions, it doesn't take long to realize that the primary overall aim of the questions is to get to know the applicant better, both as a person, and as a medical professional. This is not surprising when you really think about it. After all, these institutions know that every applicant is a qualified recent graduate of medical school. So, rather than reading about your medical qualifications, which are already covered in your cv, they are even more interested in what you bring to the table as a person and a medical professional. Failing to focus on your personal qualities that set you apart from other applicants is another serious oversight.
