Has anyone taken a really long time between 3rd year rotations/shelf exams and Step 2 CK? I am almost 3 years out due to doing a PhD in between 3rd and 4th year and now am planning on taking Step 2 CK in the near future. I feel as if I have forgotten everything from all of my rotations and from studying for shelf exams. If anyone has had a similar situation before, how long did it take to get back to your 3rd year level of knowledge/test-taking ability? I want to do really well on Step 2 but also don't want to overdo the studying since I could still finish up some extra research stuff with my PhD lab.
