I hated Cuccurullo. I couldn't stand to read more than 5 pages at a time. I'd read it some in residency. For boards, I just read the high yield areas for board. Usually, there would be a little book sign in the margin to indicated that it was high yield.
I spent almost all my time doing practice questions. The highest quality Qbank was the AAPMR one:
me.aapmr.org
I also did all the question in the Q&A book.
When I found a section I sucked like, like Peds, then I'd go do some reading, and repeat questions until I felt I wasn't so bad anymore.
There was a pmrqbankreview site that I purchased. But it was my least favorite resource.
The 100 free questions were also useful.
But, honestly, when I was taking the test, it looked nothing like any of my prep material. In fact, while I was taking it, I thought I was failing. I got home afterwards, and all I wanted to do was wrap myself in a soft blanket, hide under my bed, and cry in shame.
But I was never in danger of failing. I guess what I'm trying to say is, don't panic. You've learned a lot in residency, whether you realize it or not. 90% of first time test takers pass. Good luck!
