Hi,
Having failed the exam twice with 620 two years ago & 803 a year ago. I have been studying since completing Network+ in August.
Just decided to take the two exam option this time. Having used the 640-801 Mcgraw Hill book & CBT Nuggets up till recently &

Did the ICND course two years ago.
Would it be a good idea if I spend the last few weeks just using the 640-821 ExamCram 2 book section & Learnkey 640-821 CBT`s.
Along with Practise exams will this be enough to get me through the Intro exam? Or does anyone think I should go over the 640-811 / 640-801 stuff aswell. Already work as a Cisco network analsyt, but do very little WAN stuff.
Any Intro or general advice would be welcome.
