Sunflower CISSP Pdf
YouTube and Google for more clarity on the concept.
MG Hill questions
MGH CISSP Practice Exam 3 edition
Apart from this, I prepared more than 100 pages hand written notes for CISSP; based on wrong questions and to remember the concept.
I would recommend covering all 8 domains. There are no top 4 domains. You need to make sure you must have practice at least 3 test of 6 hours before facing real exam; otherwise exam will be very exhaustive to you.
