Yesterday i passed the CISSP exam, i must say it was very tough you can't say you have read this book or that book which helped. Exam tests you on your understanding of the concept, there are very few straight/direct questions. What you need is patience to read all the questions, analyse them and give most suitable answers, you can have one or more correct answers but there will be only one most suitable answer.
My exam tip is don't cram and understand the concept, its less technical and more conceptual and managerial.:D
Oh my exam preparation includes only the official CISSP seventh edition and few random websites where i searched for few points.
I have around 20 years of experience in IT and around 10 years in Managerial experience ( May be that is the reason i could think like a manager


)
I would also like to thank the members of this forum where i learned a lot about the exam.
All the best to everyone
