Many people advocate that anyone fresh from residency who did >75 on the last years Inservice exam probably does not neet a course. This is easy to say, but personally I view the course as one more 'piece of mind'... I did it with three other friends, and essentially it was several days of non stop hardcore studying. I did fine on the last year inservice and did even better on the qual exam. I am pretty certain I would have passed without it, but still would do the course again for the peace of mind....
i had a similar inservice track record (with far, far less prep on my part!) from the same program as you, and did fine on both qual and oral w/o any in-person prep. i'm not aware of anyone from my class who didn't pass the qualifying exam (though who volunteers this?); one person failed the oral exam that i know of (told me first hand).
i think the PTB can advise you pretty well if they think you're high risk, sounds like a big ole NO...
i did PEER VII, 1000 q's, Rivers, and another question book that i don't remember. i never read Rosen or Tint cover to cover. exam is very IM heavy, as is our practice, and our spot trains you well for this, as well as trauma and tox.
i'd say peds and elderly pts are the weak spots.
oral, i did the book that everyone does (don't recall name), rivers (cd's are good for insomnia but the practice cases are decent for flow/speed), and practiced w/ friends. felt majorly stressed after exam, but apparently everyone does.
good luck, try not to stress, and imho i wouldn't waste the $$ or days off... but that's your call
