Kaufman is good for reference and reading if you're into reading for the fun of it with all the time in the world, not for studying with limited time.
The Kaufman board exam guide is very good for the neurology portion of the exam. It's literally giving you about 1/3 of the questions on the exam. Seriously, they were so good that with the first sentence of a question that was 3 paragraphs I already knew the answer but read the entire question just in case.....only to discover my initial first answer was the right one almost all the time.
But, it's not going to teach you real neurology. Study for the board exam yes, but also study it for real to learn it for real.
