I have study material for the 2005 Network + exam and realize it's kind of out of date. I was wondering if I get good at the 2005 Network + practice tests through let's say CBT nuggets could I be ready for the Network + 2009 exam? (If it's possible by how much % should I get passing it before taking the '09 exam). Or would it just be better to take the 2005 Network + exam?...would companies really look for one to have the most recenty certification?
