Well, I took the 70-270 this past Saturday and failed with a 677. I took advantage of the "second shot" voucher, which is a blessing and a curse, because you go in there knowing that you have another chance should you fail, and that makes you not give it 100%, but it also gives you a chance to see what the test is really like. Believe me, I really did want to pass on the first try, but I was pressed for time, since the second shot offer ran out on May 31st. I used a combination of the CBT Nuggets videos and the practice tests on this website and with the Sybex book. They were good, but I feel that they didn't cover enough. A good resource that I came across on technet's website, the windows xp pro resource kit (
technet.microsoft.com/en-us/windowsxp/bb264775.aspx) really goes in-depth with xp pro. I will be studying the areas where I was weak, and hope to do the retake by June 28th. Then it's on to Security+!
