Multiple Youtube videos - Prabh Nair's, GISSP Academy etc ..
I relied heavily on ISC2, Sybex and CSA material. All the solid foundation was built based on these. On the sidelines, did the ACG course and referred multiple youtube videos to assess how my preparation is. Sybex online questions are good to make the concepts hardened. However, as mentioned earlier, these shouldn't be taken as 'learning' material.
When approaching the exam, you definitely have to think like a manager, more like a 'Risk' manager. I would recommend studying also with the same approach. Whatever topic you pick and study, always think in terms of pros/cons. For example, for Data Lifecyle, think of risks at every given step of CSUSAD.
I was able to finish my exam with almost 50 minutes left! 😎 To me, it felt easier compared to CISSP. It can probably be attributed to the fact that after studying for CISSP and the exam experience, delved into a lot more for CCSP. ISC2 exam experience of CISSP helped for sure along with the solid based CISSP provided.
During the exam, I did feel pretty confident that I'll be clearing this one. Overall, was extremely happy when I saw the 'Congratulations' on my sheet! 😀
