I took my test in December '19, but my heart is with this group right here as we all went through Step 1 together. So let this be the first score report for this 2020 thread.
Step 2CK: 271
Uworld 1st pass %: 84.9%/94th percentile (true percentage is around 85.7% due to accidentally ending a block without answering questions)
UWSA1: 274 (3.5 weeks out)
UWSA2: 276 (1.5 week out)
NBME 6: 265 (2 months out)
NBME 7: 269 (2.5 weeks out)
NBME 8: 279 (5 days out)
If I were to sum up Step 2CK in 5 sentences/"golden rules":
1) Step 2CK is all about ruling out incorrect options rather than picking correct answers
Apply this principle to every single question, even when you know the answer right away (which is rare in Step 2CK) Focus on learning how to differentiate between similar options and picking the "best answer" when multiple options seem correct/relevant. This single principle makes the difference between OK and great scores.
2) Uworld, UWSAs and NBMEs are you really need. Everything else is optional.
Dissect every Uworld explanation, without losing sight of the main concept. Details matter but not all details are made equal - focus on the details that help you pick an option over the other, and not just random factoids. Extra resources will probably not make any difference at best (and can even hurt you).
3) Practice time management from day 1.
Timing will always be an issue in Step 2CK, no exceptions. You must prepare accordingly. Even when using tutor mode, you should always go for timed mode and maintain a steady pace when solving questions. Mark the ones you don't know and solve them at the end of each block. Don't get flustered with questions you don't know - rule out incorrect options, try to see what concept is the question writer trying to test you on, make an educated guess and move on.
4) Step 1 knowledge is absolutely relevant for Step 2CK.
Keep your Step 1 FA by your side at all times. Half the actual exam contains questions you'd normally find in Step 1.
5) Properly peak into the exam, just like athletes do for major sporting events.
The exam itself is v͟e͟r͟y͟ demanding and will test your limits of sustained concentration and critical thinking. You need to be in peak shape the day you take the test. To do that, you need to avoid burnout and take regular off days religiously throughout your preparation, keep a steady sleep schedule and make sure you 're getting adequate sleep (especially during the last month of your preparation) and maintain any activities that keep stress under control, like exercise. Please don't study a͟n͟y͟t͟h͟i͟n͟g͟ the last day before the exam. Don't overhype yourself on test day - thinking about this being a high-stakes exam, only serves to increase your anxiety and you paradoxically end up underperforming. Think it's just another regular day of solving 8 Uworld blocks instead and you 're guaranteed to perform just like any other normal day at the very least. If you 've prepared properly, this is enough to ace the test after all.
