Thank you for this update! For those of us who recently purchased the 9th Edition of the CISSP official guide and are planning to take the test say August/Sept time frame. Is it possible to get just the updated portion of the ISC2 book with proof of receipt? Or do we have to buy the new book as well? Trying to figure out the best way possible and save some money. (I also bought the last minute review guide and practice test from your site 2 days ago) Thank you!
