Sometimes an activity can match two categories. When that happens, lean on the clinical categories, if applicable. (For example, if your activity is both Leadership and Community Service - Medical/ Clinical, chose the latter.) If clinical is not relevant, then choose the category in which you have the fewest activities.
A client who came to me as a re-applicant told me that a school from which she was rejected indicated that they had not counted a clearly clinical activity as clinical because she had classified it differently. Be sure you consider the categories deliberately in crafting your AMCAS.
