My experience is not good. 48 yo, 128/127/125/124, pre-med GPA = 3.76 (shaky grades when I was younger, though). 20 years of engineering experience, juggled pre-med and career, 100+ hours of Hospice, EM shadowing.
Probably 10-12 secondaries sent, three interviews (2 MD, 1 DO), no acceptances, one D.O. waitlist. I know a number of the people accepted at places I interviewed, and they were getting in with remarkably thinner GPA/MCAT/experiences, even at out-of-state MD schools.
Pretty devastated. I absolutely drove myself into the ground over the last 3+ years (continual 100 hour weeks), all for naught.
