After grammar and spelling, the next problem that needs be checked is transition. Read your essay. Go through it from end to end, and check to see if your essay flows smoothly. Does each sentence flow smoothly to the next? Does each paragraph flow logically to the next? Each statement should be connected or somehow related to the one before it, not thrown randomly together. Next, limit the use of "I" in the beginning of most sentences as it is already obvious that the essay is a piece written by an individual.
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.
