The stuff that you know will be on the exam are DEA questions. Kknow prescription requirements, facts about drugs and which schedule they fall in, how different prescribers (ie. PAs, NPs, midwifes, etc) can write for what, when, and how. Make sure you know the DEA Pharmacists' Manual and the overlapping state controlled substance policies like the back of your hand. They will ask you many questions about proper controlled ordering, transferring controlleds to other people for office use by using a form 22 rather than a script, form 224a vs form 224b, when using form 41 is appropriate versus when form 106 is appropriate, and so on. Those will be on your test, guaranteed.
Then once you have that memorized, just read through your state law book 2-3 times, making note of numbers. They LOOOOVE number questions. How long do you have until you tell the board you hired a new intern? How long can a prescriber wait to get an emergency c-II script back to you? How much codeine can you put in 100ml of syrup and have it still only be a C-V? How long do you have to keep records? How many CE hours do you need? **** like that. Trust me on this one. If you see a number, memorize that ****.
That is the basis of the straight forward questions, which, in deep retrospect, honestly did account for a decent chunk of the exam. Unfortunately, another decent chunk was mysterious crap out of left field. (I think we tend to remember these more due to tripping us up.) Like retrospective vs. prospective DURs, questions about pharmacoeconomics, **** like that. However, whe I keep in mind that 30 questions were "experimental", it makes me question if the "real" test is really that arbitrarily written on random subjects and that it's the non questions that make everyone think they failed the damned thing.
Also, I had no HIPAA questions, nor any questions on any of the congressional acts. (i.e. nothing like, what did the FD&C act do?)
Honestly, 2-3 nights is probably enough to memorize the straight forward stuff.
