I finally got off my ass and passed the CCENT (640-822 version) exam this weekend!
Bit of advice...schedule your exam. I put it off for months being nervous I wasn't ready yet, but scheduled it anyway. I failed the first time by a few questions, but from the results sheet I was able to see where I stood and it also got me back in "certification mode" 100% and I bounced back two weeks later and passed it! I used...
