I recently passed the CRISC exam, and Adam's recommendations were definitely useful. I would also explore Cybrary's CRISC course taught by Kelly Handerhan, followed by going through ISACA's Questions and Answers with Explanations Manual: https://next.isaca.org/bookstore/crisc-exam-resources/crq5ed . Like (ISC)2, truly understanding why a given answer is correct based on their explanation will be the key to success.
My local New Jersey ISACA chapter hosts both online and on-site classes for ISACA certifications with Jay Ranade as the instructor. Link: https://engage.isaca.org/newjerseychapter/events/recentcommunityeventsdashboard . I used his classes for both my CISA and CRISC certifications; both are highly recommended from me. Like most security certifications, I find it's helpful to use multiple reputable sources. +1 vote for Adam to do a CRISC course as I'm confident it'd add subscriber value.
@Morgan-Storey I plan to start Adam's CISM course in early 2020. His CISSP class was great and he supported me with exam day tips even after taking the class! I'm always advocating for ITPTV as a result of this positive experience.
