Thanks you to one and all. To reply...
I've been preparing for the exam since February and JQPlus, which was very helpful...but did not focus on Assertions and Collections nearly as much as was presented on the exam. However, those two sections happened to be where I did the best.
Go figure!
Of course, many thanks to JavaRanch to responding to my questions. I also used JCHQ's question of the day,
