80 questions. 2 hours. No breaks.
Mirroring what has been said, there isn't really one great way to prepare for it. FM is so broad, it covers peds, OB, adolescents, geriatrics.
I think the BeSci questions were properly covered in BeSci STEP 1 books. Some domestic violence stuff, a few SIGECAPS type of depression questions.
My preceptor told me that everything you need will be in front of you. REALLY focus on the stems. They are mostly thorough. Being thorough, that means there is "superfluous" data WNL. Focus on the outliers. And read the H&P stuff a bunch of x's.
Of course, I just took it so I have NO IDEA how well (or badly) I did, but it wasn't super awful. If I did well, then I'd say a general rule is similar to Step 1. Least invasive stuff is probably the right answer. I had a few answers revolving around doing nothing (like maintain meds or reassurance). If I did poorly, then maybe I'm wrong, but if you've had a great FM rotation, you've actually seen a lot of the patients in the questions. And I answered what we did w/ those patients since they were answer choices.
My preceptor made me do two presentations during my rotation. One for hypertension. One for diabetes. And I have to say that she was so wise in making me do so. A LOT of the questions of DBM or HTN had to do w/ the current recommendations. The HTN questions were based around things I got discussing ALLHAT or ACCOMPLISH studies. And I read the AAFP journals my preceptor had during our down time in between patients. W/o those, just get on UpToDate and read what the current recommendations are.
The pace isn't bad. I finished w/ 20 mins left. The images in the questions (probably 15 or so) are ones you might have seen on Step 1. And to repeat, your patients can be pregnant moms, 2 month old babies, 6 year old boys, 15 year old sexually active girls, to 89 year old ladies.
Hope all this helps! Good luck!!!
