No it’s all rubbish! Please use the highway code, a big book on natural history featuring dinosaurs and your favourite cookbook… Sure win one Lor! 😛
Joking aside, it’s the best you’ve got as a base and principles don’t change, do look at exam outline and sources NIST/ISO/GRC bits(ISACA has some great books!) - read up on the changes that have occured and remember you’re taking the certification because you’re experienced in the field / trust you assume t of strengths and weaknesses in the domain and plan you study based on that.
Postscript - personal opinion it would be better if ISC2 spent more time keeping its KB for existing certs current at least digitally and had spent less money on ads, rebranding and CC.
