They feed each other enormously, because Step 2 CK is fundamentally a test of clinical reasoning and management, the exact thing rotations train. Every patient you work up, every differential you build, every management plan you watch unfold is a living version of a CK vignette. The students who treat each patient as a learning case, reading around their actual diagnoses, walk into CK already thinking the way it tests. Plus real exposure makes the knowledge stick, you'll never forget the presentation of a condition you saw on a real, frightened patient. Run a qbank in parallel with your rotations and the overlap is massive. For US residency, strong rotations also build the clinical maturity that shows in CK scores and in your letters.
