Why the order matters
Most students treat Step 1 and Step 2 CK as two versions of the same test. They are not. Step 1 checks whether you understand the science behind medicine. Step 2 CK checks whether you can apply that science to real patients.
Building your Step 1 foundation
Give yourself four to six months of dedicated review before your target date. Spend your first weeks on high-yield systems, then move into timed practice blocks.
Shifting focus to Step 2 CK
- Review one case-based question set after every shift.
- Keep a running list of diagnoses and revisit them weekly.
- Practice under timed conditions at least once a week.
Common mistakes to avoid
- Starting Step 2 CK prep from zero instead of building on Step 1 material.
- Skipping timed practice until the final two weeks.
- Ignoring rotation feedback that points to a recurring knowledge gap.
