Many people seek to change careers and go from finance or music performance or teaching into medicine.
I'd suggest this route:
- Get a professional job that you are qualified for. Earn some money - this is not an inexpensive process.
- Arrange to shadow some physicians and, in particular, at least one who is engaged in office-based primary care. Aim for about 50 hours of shadowing to get a feel for what doctors do. (In addition to examining patients there is time spent reviewing diagnostic tests and reports, communicating with patients and other practitioners, continuing education, documenting everything!) Talk with them too about how the profession is evolving and the challenges they're seeing today.
- If your reason for a career in medicine is to help others, demonstrate your interest in helping others by actually helping others. It can be 2 hours/week helping out in a shelter or a food pantry or a program for at-risk kids or isolated senior citizens. Get out of your comfort zone and help people who can't help themselves.
- Buy the MSAR to get an idea of the courses that are required for admission to medical school and look at your own transcript to identify the gaps. Your GPA as it stands is good and could rise depending on how many courses you need and how well you do in them.
- AAMC.org has a list of schools that offer post-bac programs that will help prepare you to apply for medical school. Some will put you in touch with clinical volunteering positions and research labs concurrent with your coursework so that you have the whole package by the time you apply. I've also seen some schools provide very informative and supportive letters of recommendation. Some will also offer mock interviews and similar wrap-around services.
- Consider that you will need to devote a few hundred hours to MCAT prep. You may get away with less because you will have just taken the courses and they should be fresh in your mind but you can't skip taking at least a few practice tests (7 hours each) and spending another 7 hours going over what you missed and what you got right to be sure you know the material cold and didn't just make a lucky guess.
So, you need to determine if medicine is the right career for you and if you enjoy helping people who are different (and sometimes difficult).
Then you need to get some clinical experience (volunteer or paid), and apply to post-bac programs which are likely to take at least 12 months depending on how much coursework you've already completed. You'll want to attend office hours or otherwise get to know faculty who will write letters of recommendation on your behalf.
You'll need to prep for and take the MCAT and then be ready to submit an application in early June about a year before med school will begin for you.
One last thing: ask the post-bac programs what proportion of students who started 5 years ago completed the program and what proportion are now in medical school. Some schools will tell you what proportion of the graduates are now in medical school but some post-bacs are easy to get in, hard to stay in and the attrition rate is astounding. Get all the info you can before you accept an offer of admission.
