Glad I passed the exam and on my way to CCNA, got a score of 750. First of all I only used Comptia Network+ N10-005 edition by Mike Meyers. But be careful because there are some mistakes I found in the book, maybe like 5 (or more) I counted so make sure the material you read makes sense or look into other books. There was one part on page 93 (if you have this book), it has a exam tip that says that "For comptia network+ exam, you won't be tested on the TIA/EIA 568A or 568B color codes". And at the beginning at the exam there were 3 simulations and one of the simulations was regards to the color codes so I'm like wtf. The most difficult part was actually the simulations. The book will tell you what is this and what does it do but the sims will give you a scenario and you have to figure it out how to apply it to the best of your abilities. I believed that I bombed all three sims and passed just with just the multiple choices. Also the questionnaire that came with the book is way too difficult and does not resembles the exam but great for practice if you want the challenge. If you want some good practice I would suggest using this site sample questions, comptia free sample test (need sign up) and
CompTIA Network+ Practice Test Questions (Exam N10-005)
thnx, gl!
