Passed N10-003 this morning with 670 points
Gosh I thought I made too many mistakes! 
But then...I made it!!! 
I used the TechNotes in this site - thanks a lot folks!, the NET+ N10-003 exam guide sent by CompTIA, and SimulationExam practice test. I come to realize that if you basically understand what networking is all about then the rest is just a matter of remembering/practicing those not so often used commands and technology updates. Understanding the OSI layers is a must.
