The fact that people are putting such vastly different specialties on their lists separated by only 10-20 Step 1 points indicates a total lack of self awareness regarding what sort of career you want and what will make you happy in the long run. I considered a few highly competitive specialities during my soul searching process, and the message I received again and again was that it is only a small percentage of students that should really cross certain residencies off of their list based on flaws in their application. You are going to be doing this for the rest of your LIFE. If you really want to shoot for a competitive residency, is it really so awful to take a year or two off to strengthen your application, or plan on spending a few years in a less than desirable geographic location? Would you really rather always ask "what could have been" and have bitterness towards your speciality, than spend a few years in a community program or less than ideal state?
Do you want a narrow or broad scope of practice? Are you ok with being restricted to a tertiary care facility or geographic region for the rest of your career? Are you okay with the specialties that all but ensure you will have a boss for the rest of your life? What is your preferred population? Do you want a career that lends itself well to exploring public health questions, global health, underserved medicine, etc? What is the opportunity cost to you of 3 years of residency versus 10, and of the schedule you will have to keep to practice? Extremely importantly given the volatility of our current health care system and reimbursement: would you still prefer that speciality if its reimbursement dropped to be more equitable with a generalist IM/Peds/FP, (150-250 k), or even just a hundred k or two?
I scored >230 on Step 1, >240 on Step 2, honored >2/3 of my third year rotations, and go to a top ten medical school. And I am absolutely set on Family Medicine for residency. Those of you putting FM on your list only if you receive a crap Step 1 score and otherwise have interests in specialities with almost nothing in common make me feel sorry for you. You are going to be miserable in your career. And frankly I hope you are nowhere near my residency program.
