A lot of it was showing an honest passion for Medicine. I worked my butt off in undergrad, but every time I looked at medicine, I did everything I did because of my passion for it. I relentlessly chased being in a hospital setting. I spent a lot of time studying and learning the body systems and thinking of ethical ways to improve medicine. If you think you want to do medicine: CHASE IT. Show that you are not only intelligent and can do well on exams, but that you LOVE medicine. That you have a passion for improving something in medicine and that this is what you love doing. (I also love hard work. Like I am a workaholic).
