I assume you're referring to your ex's exam to become Board Certified in her specialty, which, if you are, makes this statement incredibly hard to believe.

A specialty's Board exam is comprised of simulated cases from that specialty. Your ex wouldn't have to prep for geriatric internal medicine or stroke rehab in pm&r. Basically everything asked in the exam for board certification is related to one's specialty.

It is not a general exam like the STEP exams.
