I'm absolutely not suggesting that this exam is "know English and you'll ace it." Certainly don't mean to suggest not preparing for it or not worrying about having a routine you got through for every patient. Yes, you should read FA and practice with SPs/classmates and come up with a routine/mnemonic for your history and physical and all that jazz.
What I AM saying is that there is room to make lots of minor mistakes and even a couple big mistakes, so don't worry about that after you've already taken the test. Even if you royally screwed up, there's no benefit at all to freaking out until your test score comes back - though I absolutely know that's easier said than done. And like I said - after the fact, if you know enough to know what you did wrong, you're probably fine.
And in fact if you look at a lot of the posts here of people who failed, it's almost always "I have no idea what I did wrong, I don't know how this happened" type of stuff. And the people who can list 25 different things they screwed up usually come back and say they passed (I did!).
