That should be enough. The Acing books are pretty readable although not that much was directly on the boards. Pay and do the ACG tests as well when you get closer. Easy CME as well. Read guidelines for things you are weak at, particularly some the AASLD ones. Lots of liver.
The test itself is fairly brutal with tons of nonsense, bad questions, questionable answer choices. This is to be expected on a board test. That said, the pass rate is like 93-98%, and when you get the nomogram afterwards, you have to be pretty awful to fail.
I never bothered with a formal review course or watching the course videos and still crushed the test, even though it felt like I was being probed as I took it. The reason these courses all "guarantee" that you will pass is because the pass rate is so high, and if you do something, take it seriously, you will probably pass.
These things are mostly a money making scam, but probably does weed out people that are awful given how forgiving it is to pass.
