The books/materials I used:
- OSG (Official ISC2 CISSP Study Guide)
- OPT (Official Practice Tests) (Amazon: https://a.co/d/5VCXSKI )
- the online training hub provided by AIO (All-in-One Exam Guide). If you buy the AIO book, you can get an active code for the questions at https://hub.totalsem.com/
I read OSG twice and then did OPT questions for each domain. Then I did the final exams on OPT. The most important thing is to understand every question that I did wrong. I decided to register for the exam when my error rate was under 20%.
The online practice platform provided by AIO is good. I can do one question, and read the answer and explanations for this one, and then do the next. I can also build a mock exam with any number of questions and any time range.
Compared with OSG and AIO, I prefer the OSG book. I think the contents of OSG are much clearer than AIO.
During the exam, if you have one question you don't know which you should choose, follow your first instinct.
I hope everyone can pass the CISSP exam on the first attempt.
Good luck!
