Like I previously mentioned, if you're already in residency, Step 3 means a lot less for you. But anyways, we know medicine is made up of a bunch of overachievers so in case you want to do well, here are a few tips: Books: You don't really need any books, and there aren't any amazing Step 3 books. Master the Boards for Step 3, as well as First Aid seem to be decent text materials for the exam. QBank: All you need here is USMLE World. The structure, layout, and material is the best you'll get for the exam. The CCS layout is nearly identical to the real deal. Make sure you do as many of these cases as possible, as it'll prep you for the second day of the exam. 1. The first day is the ONLY day you'll see statistics. Make sure you study your stats, similar to those from step 2. 2. The clinical questions are often confusing, but the curve is very generous. The most difficult part of the exam is remembering what the guidelines are, versus what you have been doing on the wards during your residency. Real clinical practice doesn't always mirror the guidelines or recommendations. 3. Timing is more important on the first day. The second day will go by a lot quicker as the CCS cases shouldn't take you the full allotted time. 4. CCS. This is the part that worries test-takers the most as you have no idea what to expect. The key here is to do as many UW cases as possible to understand what sorts of things you need to order, and the flow of how things run in the system. - Don't forget the basics. Labs, B-hCG, imaging. The history is useful, the physical less-so, unless there's a pertinent finding in there that would direct you to a diagnosis. - The key is NOT the diagnosis! You only need to arrive at a differential, and use tests/imaging to narrow your differential. They almost always provide vague symptoms so that you come up with a wide differential. Abdominal pain, headache, chest pain, shortness of breath, cough. There will be a few 'buzzwords' or hints throughout the case to direct you, but they just want to make sure you can order the pertinent tests on patients with specific symptoms, and in the right order. It's not difficult to pass if you understand what the test-makers are trying to ask. If you want to score >250, you'll need to hone down on the guidelines and have a deep understanding of diagnoses and management at a higher level. If anyone wants to discuss further on how to score >250, let me know.
