You don't need another anesthesiologist to practice with. The only anesthesiologists I practiced with were at Ho's course, and that was mostly useful because it was a few solid days of talking. You can have someone (anyone) read a script of case questions at you. The practice speaking aloud is worthwhile no matter who's listening ... and anyone will be able to tell when you start BS'ing an answer you don't know.
I think reading is not good practice for orals, unless your knowledge base was shaky to start. Talk.
There are many very predictable questions. Everything from handling desaturation, to doing an awake intubation, to approaching a bleeding tonsil, to oliguria, to a seizing eclamptic patient ... you know what to do for these. Actually saying what you'd do in a way that sounds confident, fluid, and organized is the hard part. For that you have to talk. You don't need a practice partner to tell the wall how you'd induce someone with a mediastinal mass. Practice speaking these scenarios (and others) until you sound good.
You know ACLS cold (I hope
). But if the examiner tells you your patient is in vfib and that's the first time you SPEAK out loud exactly what you'd do, you're boned, because you'll sound like a disorganized uncertain disoriented fool.
