I briefly browse the last sentence and look over the types of answers first, and I highly recommend this to everyone. As already mentioned, board questions are designed to take a certain amount of time to work through start to finish, even if it's as simple as the most common cause of purulent cellulitis. Reading the last sentence first will shave extra minutes off which can be added to more difficult questions. Same thing with the answer sets. Knowing what data you have to work with helps a lot as you test that answer set against the stem. Finally, I weed out obvious wrong answers while reading the stem, narrow to two, then take my best guess if the obvious answer remains elusive.
