Just wanted to say that I passed the Network+ exam after a quick week of study. HOWEVER, what really helped was the TECH NOTES on this site and two books:
Dumbies Network+ and Sybex Network+ Study Guide.
I did not study like I should have but at least I passed and I am moving on to Server +. I do intend to study much harder for that test.
The Sybex practice tests are hard and really help prepare you.
It accurately identified my strengths and weakness.
