Howdy -- our book doesn't talk about the upgrade exam, because we haven't actually worked on that exam yet. But all upgrade exams follow a similar
pattern:
1) Include questions from all the *new* objectives
2) Include a selection of questions from some of the other important objectives that were from the previous exam (although *all* questions will be from the new exam).
We'll have some more news for you tomorrow on the status of the upgrade exam. Right now I don't know when that's planned, but I'll probably know tomorrow. Also the previous exam will be available until the new exam has been translated into all the languages needed. That usually takes a LONG time
cheers,
Kathy
