mcts: biztalk prep

Anyone have any suggestions for prep on this?

I'm doing the 71-235 biztalk beta exam one week from now, haven't prepared.
I have two hours a day set off to prepare. That should be about 15 hours.

Goal: To learn what biztalk is all about. I plan to pass the exam at a later
time.
Exam-score goal: 450

Plan:
1) One hour to write the plan (this blog).
2) One hour to set up biztalk in a virtual image.
3) Three hours of webcasts.
4) Ten hours with virtual labs.
5) Do the exam
6) Update blog
