I run MedicalSchoolHQ.net. ApplicationAcademy.com is an online course that I run to help students get into medical school. I've used an image I'm posting below.
Update: One of the symbols used in medicine is a white coat. I'm wondering what can be done to include some path to a white coat?
The imagery we generally use for the application process is a map, or a mountain to climb. There are several parts to the application process, so it could be a multi-step process.
