These titles are fine for the core rotations, but I actually know of no one who used these for step 2. The common texts are FA, Crush, Secrets, Boards and Wards, Deja Review. But I'd say 90% of your studying for step 2 should come from World/qbank explanations. Doing problems and learning from the explanations is how most people get the most bang for the buck for CK.

I know one friend who re-read the case files series (took about 2 days per book) and then did all UWorld who did well. My strategy is Secrets/Uworld, but if I have some free time during my next 9 weeks of required rotations I will re-read case files for the earlier rotations.
