Today I passed my CEH v6 with 99% score.
1. CEH Exam Prep (Michael Gregg)
2. Official Certified Ethical Hackers Review Guide. (Kimberly Graver)
3. Ec-Council's C|Eh 312-50 Instructor Slides (Only few chapters Voip/Mobile etc.)
4. EC-Council's 6 DVD CBT video (Helpful to understand stuff)
I would say please use CBT because. It's helpful to understand stuff. CEH exam prep and Review guides are awesome one. one more thing please use google for more help about study because those book will not cover all stuff like Blackberry/bluetooth/GPS are not in those book.
They asked lots of question on Nmap/Hping2/buffer overflow,SQL injection Technic also they asked honeytoken question which was new for me.
Best of luck :)
And they for all of you who helped me direct or indirectly.. Good luck :)
