Re: How to pass CISSP - Just obtain CISM last month
There are many resources available for the CISSP - both self-study and in person. Personally, I found that the self-study options are better >> they cost a lot less, you can study at your own pace, and they are more widely available (mostly books you can get online). I stuck to the official materials more or less, and it worked for me.
If you would like to read about my own experience for more context, please feel free to do so. I talk about the specific materials I used (or would have used, had I known about them).
