Hi Architeer,
I spent about 3 weeks studying for this test and passed, it was stressful but definitely possible. Those Schiff Hardin lectures are invaluable for the test. To add to what others have said, I hit "hot" topics in a couple of the CSI manuals
http://www.csinet.org/Main-Menu-Category/CSI-Store/15 and listened to a couple of webinars from the AIA site. Don't forget that NCARB allows you to download samples of the contract documents to review, and the AIA has a nice set of commentaries on what everything in the contracts mean! Anything I ran across that I didn't feel confident with, I did a few minutes of additional research on the web to round out the topic.
There were some planning questions also and a decent amount of code questions. Every test so far (5 in all) have hit heavily on ADA requirements.
There were a number of questions on my exam related to project delivery, insurance/bond requirements, phasing of a project, and specifications. AHPP is invaluable! Also, as others have said in other forums, make sure you review the materials NCARB suggests:
AHPP (Architects Handbook of Professional Practice - Coach has this listed on his references page
http://astore.amazon.com/calarcce-20)
Architectural Graphic Standards
Building Construction Illustrated
CSI Manual of Practice
Rules of Conduct
Good luck!
