Which Exchange 2007 exam first?

[ReadyorNot]

Hi there,

I'm about to embark on the rocky road of studying for the Exchange 2007 exams and was wondering is there is a recommended order for attempting them in? So i'm looking at:

70-236: Exchange Server 2007, Configuring
70-237: Designing Messaging Solutions with Microsoft Exchange Server 2007
70-238: Deploying Messaging Solutions with Microsoft Exchange Server 2007


I've read that 70-236 is a beast of an exam, so I've kind of been leaning towards starting with 70-237. I have a lot of hands on experience with Exchange 2003 but don't have that MCP. My work have recently migrated one of our servers to 2007 and will shortly be doing the others too so i would like to get myself up to speed with 2007 as quickly and efficiently as possible.

Thanks in advance.
