I'm in process of planning out my action plan for CISSP.
From all my research, I'm planning to use this material:

Books:
CISSP Study Guide 3rd Edition - Eric Conrad
Eleventh Hour CISSP: 3rd Edition - Eric Conrad

Exams:
Boson - $99 - 15% coupon
CCCure - $60 for a month
Cybrary - Free
Skillset - $99 a month

And I'm thinking to also register for one of these two (studynotesandtheory.com and internetworkdefense.com) and wanted to know which you select and do I even need to go with one of these two, since I'm already reading two books and will work on four exams types.
