Making my way through the 70-236 book.. on page 117 out of 750, Chapter 3 out of 13.

Also, a great blog post on Do you have what it takes to become a Microsoft Certified Master? at the Microsoft Exchange Team Blog - http://msexchangeteam.com/

Interesting note on the program fees for MCM (Master) and MCA (Architect):

• Microsoft Certified Master: All - $18,500.00 (USD)

• Microsoft Certified Architect: All - $5,000.00 (USD)

I say it's interesting because MCA was reported at being $25,000.. not $5000.

Still, that's $23,500 in total.. yikes!
