I was scheduled for the 407 on Thursday - registered online with Prometric. Found out Thursday AM that while I could provide them with my confirmation info from their site, they would not let me test because of a problem between their "web registration group" and their "customer service registration" group. Bottom line is they gave me a free 407 exam for MONDAY at 4:15 PM. I'm fairly confident in my ability to pass the 407, but this has almost put the frosting on the cake as I have considered taking the 507 instead. What additional material is on the 507 that is not on the 407? What I'm considering is going to 507 route - that way I won't have to prepare over a weekend when I'm going to be on the road, and I'll have gain the knowledge required to satisfy the 507 requirements. ANY and ALL help appreciated.
