Passed my 70-620 test this afternoon. I scheduled it a few weeks ago and planned to start studying however I got busy and kept putting it off. Starting Friday - this morning I started watching the CBT nuggets @ 2x speed and passed

So if someone says the CBTs aren't enough to pass, they are.
I've been working with Vista since it's release but never used a lot of the features that were covered in the test. However they are all pretty easy to use.
Easy test overall. Had probably 15-20 sims.
