But what if I REALLY want to doubt you; am I allowed?
Bob Kuske used to diagram a pyramid on a chalk board. At the base of the pyramid were like super-easy oral questions; if you missed those, you failed for sure (and would score a 68 in that category). Anyways, the pyramid had five levels. Once you got up to the apex, you were kind of in an esoteric category and the examiner was just letting you show off. You had definitely passed at that point. Getting something wrong in level 3 put you borderline for 69 (fail) or 70 (pass), but didn't always necessarily mean you would fail. Additional questions would be asked to show if you had that level 3 (midway up the pyramid) knowledge. If you got to the top level, you got a 72. If you got a couple 72's in some categories and a 69 in one category, but 70 or higher everywhere else, they'd usually pass you outright. So, this was years ago, and I doubt Bob still is an oral examiner. But there's some definite truth here. Don't doubt me! Bob used to really harp on this "levels of questions" thing.
EDIT: I do believe if you get a question about how to treat an IMN recurrence that abuts a previous XRT field two years after whole breast RT for a T2N0 ER+/Her2- patient you're going to pass the breast section.
