How to Score a 280 on USMLE Step 2 CK

Having scored in the 270-280 range on Step 1, Step 2 CK, and Step 3 of the USMLE, I am often asked by students questions like “What’s your secret?”, “How can I plan my study schedule to score that well on the USMLE?”, “If I scored xxx on Step 1, how long should I study for Step 2 CK?”, and “What’s the best study plan for Step 2 CK?” 

I’m going to be honest: if I had a single secret or silver bullet, I would tell you. The harsh truth is that if you want to score in the >99th percentile on the USMLE to help you score the residency program of your dreams, the work will have to begin early in medical school with concerted efforts to build a solid knowledge base which you can then consolidate during your dedicated study periods. 

Chances are, though, if you’re reading this post, you are preparing to take Step 2 CK within the next few weeks to months, and are looking for actionable advice about how to set yourself up for success in the here and now. So, don’t despair! While I (unfortunately!) don’t have a single gimmick that can guarantee a high score, I can emphasize (1) the strategies that I employed to be a successful test-taker for the NBME and (2) patterns of study behaviors I have observed in the dozens of students I have tutored that tend to lead to more or less successful test performance. 

Of note, I have written a separate blog post regarding strategies specifically for Step 1, so this post will focus more on effective strategies for Step 2 CK. 

 

Building a Firm Step 2 Foundation: The Importance of Clerkship Year

In comparison with Step 1, Step 2 CK is more clinically focused. The typical Step 1 question will involve basic pathology, microbiology, disease pathophysiology, pharmacology, or similar basic science concepts. While basic science questions still show up on Step 2 CK, the most common question types are “What is the most likely diagnosis?” and “What is the next best test?” rather than “What is the mechanism of action of the appropriate antibiotic?” or “What is the makeup of the genome of the most likely causative virus?” as on Step 1.

Given this, success on Step 2 starts with concerted studying throughout clerkship year. As we know from adult learning theory, interleaved practice is crucial to consolidating knowledge and making memories stick. This involves making associations between patients and disease processes you see on clinical rotations and the textbook versions of their diseases you read about in clinical resources like UpToDate, journal articles, review books, and question banks. Studying hard during clerkship year pays dividends in both directions: clinical experiences in which you can put a face and a story to a disease increase the salience of the medical information you are reading, while gaining a deeper understanding of patients’ disease processes will make you a more engaged and effective physician. 

Because of this, there is no better time to consolidate clinical medical knowledge pertinent to Step 2 CK than during your core clinical rotations. Many students choose to use the UWorld Step 2 CK question bank to aid in clerkship study and prepare for shelf exams. I strongly recommend using the QBank in this way. Doing a “first pass” through the 2 CK question bank during clerkship year will (1) ensure that you have made it through every question at least once before your exam, and (2) help you integrate the knowledge you’re learning in each clinical discipline with the specific subset of knowledge the National Board of Medical Examiners thinks is most pertinent for each discipline. 

This is important because the specific topics emphasized by your clinical instructors will inevitably not have perfect overlap with the full breadth of topics necessary for Step 2 CK success: while a rotation on vascular surgery, for instance, may emphasize a detailed understanding of blood vessel anatomy and nuanced considerations for intra-operative decision-making, the surgery questions on Step 2 CK are more apt to focus on big-picture indications for vascular surgery (e.g., recognizing compartment syndrome) and post-operative complications. Moreover, the exam will cover all subspecialties: there will likely be questions on trauma surgery, for instance, to which you may never be exposed if your core surgery rotations are in pediatric bariatric surgery. Using the QBank to guide your clerkship studying will thereby help ensure you have a solid framework for the breadth of topics covered in a particular discipline and help make up for the idiosyncrasies of your individual clinical experiences.

In addition, using the UWorld Step 2 CK QBank during clerkship year is advisable because there is evidence that USMLE performance increases directly with the total number of questions performed. This is sensible when considering that the NBME has (1) a predictable, and therefore learnable, style of question-asking, and (2) certain favorite topics which can be mastered with repetition. That is, the more exposure you have to USMLE-style questions in the months prior to your exam, the better equipped you will be to handle the hundreds of questions you will have to answer back-to-back on test day.

Creating flashcards as you go along with a spaced-repetition feature like Anki is a great hack to consolidate long-term retention: if you make flashcards with QBank pearls from each clinical discipline in turn and keep up with them throughout the entire year, then your long-term retention of the material will be outstanding, and your exam prep will be all the easier. 

 

When Should I Take Step 2 CK?

Given that clinical experiences are so key to Step 2 CK-relevant knowledge, if at all possible, you should aim to take Step 2 within 6 months of finishing your core clinical rotations. The rationale for this is self-evident: it is much easier to review the topics covered on the exam when your intensive introduction to the disciplines in question was relatively recent, rather than years away. If you have a medical school structure in which Step 1 is taken after core rotations, then if you have the stamina, taking Step 2 within a few months of Step 1 is also advisable, as there is substantial overlap in topics covered.

One caveat here: clerkship year is exhausting and may contribute to burnout. If the prospect of jumping immediately into Step 2 study after finishing rotations is too daunting, then taking some time for reset and recovery on lighter rotations before jumping back into intense study preparation is sensible: our brains absorb knowledge best when we are well-rested, curious, and engaged, not tired, burned out, and exhausted.

 

How Long Should I Study for Step 2 CK?

No matter when you take Step 2 CK, if you want to score in the 270-280 range, it is critical to have a dedicated study period with no other significant obligations to consolidate your knowledge and hammer home exam prep. To determine how long that period of dedicated study should be, it is important to reflect on your comfort with the material, the length of time since your core clinical rotations, the length of time since you took Step 1, and the amount of time you needed to study for Step 1. If you scored in the 260+ range on Step 1, are only a few weeks to months out from core clinical rotations, and needed only 4-5 weeks for dedicated Step 1 prep, then as few as 1.5-2 weeks may be sufficient for Step 2 CK prep. By contrast, if you scored <260 on Step 1, are several months out from clerkships, needed 8 or more weeks for Step 1 prep, and are serious about boosting your score by 20 or more points, then a dedicated period of at least 4 weeks is advisable. If your schedule does not allow for a prolonged dedicated study period because of clinical or personal obligations, then incorporating study over 6-8 weeks is sensible. Prolonging dedicated study more than 2 months is not advisable, however, as the likelihood of forgetting topics studied at the beginning of your review period increases with increasing time spent studying. 

 

What are the Best Resources for Step 2 CK Exam Prep?

In my experience over hundreds of hours of USMLE tutoring, students commonly fall into the trap of assuming that more resources = better exam performance. “If I review ‘everything’ in each of these study resources, then I’ll be more prepared than if I only reviewed a single resource”, or so goes the argument. This is a fallacy. The highest yield resource for Step 2 CK is far and away the UWorld question bank. Getting through the entire QBank and really understanding each question should be your top study priority. Beyond the QBank itself, the official exams offered by the NBME are the best possible predictor of our score on the actual exam. I recommend taking at least two practice exams, as these will simulate the stress of the actual exam better than simple UWorld question blocks. Taking a practice exam ~2 weeks prior to your exam will also be a good indicator of how close you are to your goal score – if you score >20-25 points below your target score with 2 weeks remaining prior to test day, it is likely worth postponing your exam by a week to allow for additional time for review.

Additional high-yield materials that can supplement your studying (e.g., for additional review of problem topics) but should not be considered primary resources include First Aid for Step 2 CK, Online MedEd, USMLE Step 2 Secrets, and Master the Boards Step 2 CK. If you need additional information, all resources are listed on our reviews page. Many students find these resources as helpful in organizing the material presented in UWorld.  However, they should not be your first priority – I scored a 278 without giving any of these resources more than a cursory look-over. 

 

So in summary, acing Step 2 CK requires:

  • Prioritizing studying throughout clerkship year to build a firm clinical knowledge base, ideally building a comprehensive Anki deck for longitudinal review
  • Minimum 2 weeks of exclusive exam prep time
  • Exhaustive attention to the UWorld Step 2 CK Question Bank
  • Taking at least 2 official NBME practice exams
  • Giving yourself enough time off before studying in earnest to avoid burnout

 

Best of luck with your USMLE prep – and may you land the residency of your dreams!
