Passed the CISSP yesterday. Was a tricky one. Finished at 100 questions.
Studied heavily for about a month. Here is what I used, all are recommended:
1) Sybex Official Study Guide v8.
2) Boson practice tests.
3) Mike Chapple video courses on Linkedin Learning. (This was very good. He wrote the book!)
For the Mike Chapple videos; ; if you haven't already used it, I recommend using your 30 days of free LinkedIn Learning for these.
