ABEM is and always has been a joke of an organization that exists by overcharging already debt-ridden new attendings for certificates with little added value.
I was once told by an oral board examiner that ABEM oral boards were his favorite week of the year because of all the free food and lodging they get. Apparently there's a steak dinner that runs $200+ per head that ABEM covers them for. Not to mention, when I took my oral boards, I got there and saw some of the most incompetent attendings I've worked with as examiners. In no world should they have been certifying anyone.
In case you ever wondered why you were out of ~$5k to get a board certification, it's so these fat cats can eat fancy steaks and drink great wine on your dime.
I recertified a few years ago to keep active though I don't know when/if I'll work clinically. Probably won't bother next time around.
