Sat the 70-620 today and was successful with an 828. I had a really hard time studying for this one to be honest, not because it's difficult by any means but because I really had a very hard time becoming even remotely interested in the material. The only thing that carried me through was wanting the MCITP: EA and it being one of the requirements, I almost wish I would have taken the deployment exam, but I already had the MS Press 70-620 book so I gruelingly went through it anyways.
Study materials included the first 3 chapters of the MS Press book, I was literally being put to sleep. Also went through the TestOut 70-620 CBT in it's entirety once and went through the practice exam on it 4 or 5 times. I probably could have used a but more reading from the MS Press book on the parts of Vista I don't use much (meeting space, etc).
On to focusing the bulk of my efforts on the 70-640 while doing a bit of study for the Windows 7 client beta exam and the Server+ beta exam which are all upcoming this month as well.
Feels good to have one under my belt though. Oddly enough I've been around the industry for over 9 years, the first 2/3's of that spent mostly in the small business sector and the last third spent at a larger corporation but I haven't completed any certifications up until now. Haven't had the need really since I've acquired my jobs through business relationships, but I've been encountering problems working further up with a lot of other candidates having degrees and certs. That began my journey to complete my B.S. which will be finished up in several months as well as getting some certs
