I considered holding off on heme until next year but I figured I'd give it a shot and get it out of the way. They asked a lot of esoteric questions that would make for mind numbing mental masturbation between academics but really have no relevance for the majority of practicing docs, and more importantly have no relevance in the care of patients.
In all fairness, the exam did touch on some important practicing topics, but I felt in general it didn't seem like they were testing (both heme and onc) you to see if you knew and understood the topics, and most importantly if you could navigate the treatment of a patient in different scenarios.
In comparison to all the steps and medicine boards, I think the authors of the exams failed to write questions that gauge good safe physicians as opposed to trivial pursuit/Jeopardy champions.
