I've finished the 6 e-learning courses for the 70-237 exam.

• Course 5063: Designing Servers and Message Routing in a Microsoft Exchange Server 2007 Environment
• Course 5064: Designing Security in a Microsoft® Exchange Server 2007 Environment
• Course 5065: Designing an Exchange Server 2007 Coexistence and Upgrade Strategies
• Course 5066: Designing Microsoft® Exchange Server 2007 Policies
• Course 5067: Designing a Highly Available Microsoft® Exchange Server 2007 Messaging Environment
• Course 5068: Designing a Disaster Recovery Strategy for a High Availability Exchange Server 2007 Environment

I'll spend the next few evenings taking the practice tests and checking the books for any portions I'm weak on.

With any luck, I'll be ready to take the exam by this Friday or the following Monday.
