FA has most of what you need to know, but I had a few drugs appear on my exam that I had seen only through QBanks, so know anything that shows up through questions as well.
Know the different prostaglandin analogues and monoclonal antibodies. These are the highest yield of the lower-yield, so if you're curious as to where to expand your knowledge beyond FA, that's your money.
I had made a post a couple weeks ago about a drug I had never seen before having shown up on my real deal. I ended up choosing this drug because the other ones just didn't seem right. I was trying to avoid looking it up because I didn't want to be all disconsolate if I was wrong, but it turned out, LUCKILY, that it was the right answer. Bottom line: there will be stuff that shows up on your exam that you've never seen before, no matter how much you've studied. Know the drugs in FA + those you learn through questions and their explanations, and go through the Lange pharmacology cards if you want a top-up/boost. Don't bother with the Brenner cards.
