I was so thrilled when I received my score report.
My study resources:
Safari course by Sari Green (all 3 of them, old and new) - This was my primary learning source and highly recommend it
Larry Greenblatt videos - ehhhh. I paid $99 for his videos. He knows his stuff, but if I paid for his full bootcamp, I'd be mad

Boson - excellent practice tests - highly recommend this
Sybex Practice Tests - I know this product gets a lot of hate, but I recommend it. I bought the kindle version, but only used the online testing engine. It definitely has bugs, but wasn't too bad
Sybex CISSP 8th Edition: I did not read this book cover to cover, if I read 10% of it, that's a lot. I only read up on topics that I knew I was weak on after I took the practice exams. However, if I did it over again, I'd probably read this book cover to cover. The only reason why I didn't is because I'm a slow reader and wanted to complete this exam in 2018
