Agree with the above. Your Step 1 won't help you at all for DO or MD since it's way below the average. I wouldn't even waste apps on MD.
Apply to the previously AOA programs and crush your auditions. AOA programs are not all about scores. I know many ortho residents now who had <600 COMLEX (but they were really cool to work with, had research, connections, etc.)
Biggest things you need to focus on now.
1. Getting SOMETHING in research
2. Learning the basics of orthopedics like fracture classifications, basic management, and how to read and present xray images.
3. Network
4. When it comes to fourth year, rotate at programs that have a low number of students (for example, NOT places like Doctors that have hundreds of students)
