Being an Apologist _ You do not use your personal statement to explain why you lack certain skills or experience. The point of writing this short paragraph is to sell yourself and this involves highlighting your strengths instead of apologizing for your weaknesses which in itself is a sign of weakness. The time and place for discussing flaws in your suitability is the interview and at that point, you must focus on how you plan to overcome any holes in experience/skills etc.
Sell Yourself Your main goal is to sell yourself to the medical school, but do so in a way that is not arrogant. You must strike a balance between selling them on yourself as an applicant and not sounding cocky or pompous. The mistake people often make is that they think selling themselves involves listing grades and honors. It does not. Rather, it involves telling the reader about you as a person. Remember, the admissions committee already knows how you look on paper, they now want to know who you are. This is the place in your application where you have freedom. You can be humorous, you can be serious, or you can be philosophical. The key is to just be yourself. Let your personality shine through
