I passed the CISSP today 03/23. I studied for roughly 3 months using various resources.
I wanted to thank this study group for the practice questions.
Here is a jumbled list of the resources I used and probably forgot a few.
Exam Questions:
Learnzapp and CISSP app
The Destination Certification App also comes with over a thousand free questions and flash cards that are somewhat like the exam
LinkedIn Learning Practice Exams (pretty good)
Books
ISC2 CISSP Certified Information Systems Security Professional Official Study Guide, 10th Edition by Mike Chapple (I read this whole book and used the companion site for questions)
