Academic competition event organization is awesome, but it doesn't show service orientation as defined by the AAMC preprofessional competencies. This is typically satisfied with food distribution, shelter work, job placement services, transportation services, or housing rehabilitation. Your food insecurity advocacy gives your social advocacy activity more authenticity.
Is there anything else you have done for at minimum 150 hours that shows your ability to work comfortably with other communities when it is not comfortable for you? I'm guessing or hoping your nondisclosed activity covers this?
It seems your clinical experience is also light. Can you tell me more?
The IA... that is going to hurt a bit. Was this during the pandemic, since this was 2 years past?
The overall impression is a strong identity in the sciences as a member of the chemistry community, so strong science competency and advocacy. The identity of aspiring physician or health care provider is not so obvious from what has been disclosed. Connecting with an MD/PhD goal... not clear to me. Our experts in the Research Scientists forum may offer different advice.
Either take the year to work on these activities, or apply as a chemistry Ph.D. Really why not? Or go to a masters and work in industry to continue your work promoting science to young students? We need that too.
