Just sat the 70-630 Configuring Microsoft Office Sharepoint Server 2007 exam. 964 out of 1000, so 1 question wrong. Damn that’s frustrating!
I’d rate it about 4 out of 5 on a hardness scale. The range of questions are quite a bit broader than the WSSv3 exam. Then again MOSS2007 is such a huge product when compared with WSS.
