I finally got through the Core, OS, Net+ with a 609, 605, 606. I don't even work in IT (career move) and I studied my a** off and got it. I was suprised that all the practice tests that I have taken, I didn't even run into any questions that even resemble those. The Core and O/S are pretty much the same as othre sights. I also was suprised on how many questions that covered MAC OS, Linux/Novell servers, Novell commands, and security (IPSEC, L2TP, Kerborous, MSCHAP, PAP). All of which were very briefly mentioned in class. Since the Net+ has recently changed, I assume that the online study guides and exams were outdated.
