The CSA and "revision"

I hear of GPRs "revising" for the CSA. I wonder what they are doing in that learning space. The CSA is testing what the GPR does on a day-today basis in the consultation. It strikes me that the best way to pass this exam is to see patients, reflect on the process, define the learning needs, address those needs, then try them out - the learning cycle. Becoming competent requires this upward learning spiral, and the eportfolio makes the process explicit. I'm not sure that "cramming" is going to help.
