Passed my CCENT today with 925/1000. My two cents:
Background:
I'm a java developer, I have no professional network experience.
Before this I never touched an actual cisco device (besides using a voip phone

)
But I have to admit that due to personal interests I allready have broad network knowledge (at least on a basic level)
Study material:
CISCO press (odom) - ICND1
Boson exam sim which was included with the books
This forum, so a big thanks to everyone on this forum

Internet / CISCO website for commands and deeper understanding
Hardware:
I borrowed a 1720 and 2621 from a friend.
Later on I discovered GNS here, so I also used that with 26XX and 7200 IOS. Especially to test SDM since I cannot use it with the 2621/1720.
Time:
I read the book completely in july/august, then gave it a rest.
Then I started the actual preparation two weeks ago.
Exam:
I felt it was very easy. Also got plenty of time left.
I got one very weird question of which nothing is mentioned in the ICND1 material whatsoever, but the exam warned that there could be experimental questions, so I guess thats one of them.
I think ICND2 is going to be harder

(but I hope not)
