As mentioned in a previous post, I'm studying for the 70-620 Configuring Vista certification exam. As part of this process, I've read 85% of Mark Minasi's book, Mastering Windows Vista Business. The book starts rather low tech, moves toward more work related topics and higher level information as the it progresses. It covers a lot of information, and at 1020 pages it should. I don't know if this was the best resource for studying for the Vista exam, but it was on my shelf waiting to be read. As I mentioned I only cleared 85% of the book, which is 867 pages, because the last section covers automated corporate deployment options with images, etc., which is not covered in the 70-620 exam; I was getting short on time and CBT CD to watch. All-in-all another good book by Mark Minasi, his easy style and readability makes all of his books great resources.
I've also watched 15+ hours of video using a CBT Nuggets product with James Conrad. This was quite the undertaking (3 hours the first day, then two 6 hour days), most of the content I was familiar with, but there were a few gems I may need for the exam or work in general. James is quite chatty, cracks himself up and sometimes makes some amusing metaphors and examples, one was (I'm paraphrasing), "Imagine having a three year old that just ate a box of Twinkies." I give this product a mild recommendation, as it was interesting most of the time and the presentation was definitely workable.
Additionally I've read free guides from ProProfs and took a couple of sample tests from MeasureUp. Both of which were worthwhile.
Now with all this time in, I'm feeling pretty good about passing the test, I'll know tomorrow afternoon for sure...
