AAMC has developed four categories of Core Competences (Interpersonal, Intrapersonal, Thinking and Reasoning, and Science) for entering medical students. Check them out!
A successful applicant to medical school can demonstrate they are excellent in many or all of these core competences. How will you demonstrate in your application to medical schools that you are "Competent"? Think about the activities you have engaged in and the experiences you have gained during your time at Barnard. How can you "show" you are "competent" through these experiences?
Feel like there is room for improvement in a particular area? Good for you! We all have areas to improve upon! This is the perfect time to set a goal(s) for yourself to improve in this area through engagement in an activity (whether its a new one or current) so that you can demonstrate you are a strong applicant and will be a successful medical student and future doctor!
