I received an II as well... Sept. 5th.
For the 1 page resume, include academic metrics (GPA, MCAT etc.) and schools attended with degree awarded. Also include extracurriculars (internships, volunteering, research, shadowing hours, medical-related jobs etc.)
Include any awards you received, clubs joined, etc.
Picture top right or left.
Also include an objective if you have the room for it. (e.g. "I am currently a student at xxxxxx and plan on attending medical school to pursue a residency in xxxxx" or something of that nature).
The order for mine was:
Objective
Academics
Clinical Experience
Activities/Affiliations (volunteering, research, clubs, etc.)
Make sure you weed out anything that is less important so you can leave room for the more important stuff.
Let me know if anything is unclear!
Good luck to everyone this year!
