Without details about your activities, I think many of your activities might be co-mingling (clinical/non-clinical for your community health org/podiatry clinic work). Mentoring and tutoring are prominent activities but won't help you stand out in the application process. I'm not sure what your purpose is as a physician, so it's not clear that you have a strong mission fit with schools on your list. Your MCAT is not the issue; lacking opportunities where you stretch beyond your comfort zone might be.
