Reddit take
AI summary of the Reddit excerpts below — not a quote
The ISC2 CISSP Official Practice Tests are widely considered a foundational resource for identifying knowledge gaps and reinforcing technical concepts from the Official Study Guide (OSG). While highly effective for verifying domain-specific knowledge, many users find them unrepresentative of the actual exam's difficulty and scenario-based question style.
Pros
- Directly aligned with the Official Study Guide (OSG) content
- Excellent for identifying specific domain weaknesses
- Effective for technical knowledge checks and terminology reinforcement
- Provides a structured way to review after finishing individual chapters
Cons
- Does not accurately simulate the scenario-based 'feel' of the actual CISSP exam
- Questions are often described as 'flashcard-style' or overly technology-focused
- Difficulty level is generally considered lower than the real exam
- Occasional reports of inconsistent reasoning or poorly phrased questions in some editions
Caveats
- High scores on these practice tests do not necessarily indicate readiness for the actual exam's complex decision-making questions.
- The resource is better suited for knowledge retention than for learning the 'managerial' mindset required for the exam.
Best for
- Candidates using the Official Study Guide who want to verify their understanding of the material
- Initial study phases to identify weak domains
- Reinforcing technical facts and definitions
Avoid if
- You are looking for a realistic simulation of the actual exam's scenario-based difficulty
- You need to practice the 'BEST/FIRST/NEXT' decision-making strategy rather than technical recall

Going with this over the Official Practice Tests, which are tempting to re-take because it will cover off the knowledge base and keep it fresh, but I feel like the more important piece (if you have to prioritise one) is the approach to solution selection.
Official Practice Tests: These are straightforward and directly linked to the official text book, making them excellent for checking any gaps in my knowledge.

That and the Official Practice Tests were my favorite resources.
Official Practice Tests: Honestly not reflective of the real exam. Good for knowledge checks, but not for exam feel. (5/10)
The exam from the OSG book and official practice test only reaffirms your knowledge.
This is again from 3rd edition of Official practice tests. ... This question missing one of those words points out that it's not written well for the CISSP exam.
I have this from the 3rd edition of Official Practice Tests. Weird that the answer is different in both places along with the reasoning.
I tried official practice tests but they are mostly flashcard type questions and after the exam, I realized that they were not matching the exam difficulty level at all.
