I was looking at:

MCITP Self-Paced Training Kit (Exams 70-431, 70-443, 70-444): Microsoft® SQL
Server 2005 Database Administrator Core Requirements

As a way to study for Microsoft certification, however, I've seen some
questionable reviews on the accuracy in portions of the books, which
confuses me.

In short, I'm unemployed and, given the economy, expect to be for 3-6
months. So, I want to use that time to maximum advantage.

Have I made the correct choice?
