Hi folks, I am getting back on track to the cert world after a few years of "retirement", and headed to get the MCSA quite soon. I've already knocked 290 & 291, and planning to take 70-680 for Windows 7, as compared to 270 which I think can bit it so easily. What books do you guys recommend that can help me prepare for the exam? I was gonna get the the Self-Paced Training Kit from MS but got a lot of conflicting comments about it on Amazon and not sure what to pick. Thank you and the help is greatly appreciated.
