I enrolled in a premedical postbaccalaureate program, and over the course of two years of night classes finished all of the prerequisites required by most allopathic medical schools. I worked by butt off to finish with a 4.0 GPA and place in the 96th percentile on the MCAT (good enough to not be ruled out because of my MCAT score). I also volunteered at a memory care hospice on weekends during this period and ended up with 100 hours of clinical experience. I had some additional clinical exposure working on medical device projects as an engineering student.
I applied to 27 schools and was invited for two interviews. Of those two, I was waitlisted by one and rejected by the other. I didn't end up clearing the waitlist. So what went wrong? I can't say for certain, but I suspect these were contributing factors:
* My undergraduate engineering school GPA was 3.3 and my graduate school engineering GPA was 3.4. These are reasonable by engineering school standards but borderline for medical school. * I only had 100 clinical hours. Many applicants have hundreds or even thousands of hours of clinical experience when they apply. I was 31 when I started the postbac program and decided to keep my full time job in order to save up money. The opportunity cost of each hour of clinical experience was higher at this age compared to a typical undergrad. In hindsight I should have at least devoted my weekends to gaining clinical experience the moment I decided to go this route. * One of my recommendation letter writers was late. My application wasn't processed until all recommendation letters were in. I wasn't eligible for consideration until later admissions rounds. * I didn't stand out. To be clear this isn't a requirement, but schools like to build a diverse and interesting class, so standing out in some way can be helpful. I struggle to decide if this was something beyond my control or if it represents a personal failure.
To return to my initial point, it is doable. In an alternate universe in which my recommendation letters made it in earlier, or I slept better before the MCAT and got an extra point, perhaps I would have been invited for one or two more interviews. If the interview -> admission invite conversion rate is 20%, that boosts the odds of admission from 36% to 59%. (I haven't ruled out applying again, but I would need to enroll in classes for at least another year in order to get new faculty recommendation letters. Unfortunately it isn't safe to volunteer at the hospice right now due to COVID-19).
