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.

Keep it simple and let it serve merely as a quick reminder of where you're going. It might run like this: First memory _ seeing my new baby brother in my mother's arms. Nursing experience _ volunteer in residential nursing home. Visiting the baby clinic _ desires to become a midwife sufficed. Goals for the future _ career ambitions.
