I did the SCCM board review course on demand, played most of the lectures throughout fellowship, then listened to them all again as I drove across country to start my first job. On top of that, did all of SEEK, the SCCM AKAs, an ATS question book, an old ABA CCM self-assessment module, and a crappier online board review question set. After all of that, the actual exam was almost a breeze, and I had a ridiculous amount of CME that I could claim.
