Posting my experience for encouragement for those who are nervous about the exam or have failed the exam. I was very stressed out. Make sure you know all of the info, not just skim across some subjects because the one section that is skimmed over can be the determining factor of weather you pass or not. I failed the ICND2 twice (I hate admitting that
but it happens and I didn't give up). I failed by maybe one question the second time. I had two questions of the tiny bit of material I skimmed over. I look at failing twice as I now know the material much better. You'd be surprised at how much info you thought you knew but when re-studying after a fail you realize there is A LOT more to the concept than you thought.
Study material:
Todd Lammel's CCENT and the CCNA books
Wendell Odom books
CBT Nuggets
Packet Tracer
CCNA Portable Command Guide <-- I highly recommend this because it is great when you need a quick reference
Never give up!!
