Bridgett,
Sorry to hear the upgrade thing did not yet occur- keep at it- it will.
Now, unless they have changed the exams substantially (and that is likely since I took it so many hears ago), from my memory, here is what to expect:
Since all these exams come from a single database of questions, what they can do is to gear the upgrade parts to the more difficult (in their minds) questions. Typically, that revolves around the income questions.
So, I'd bone up on those a bit- obvoiusly not ignoring the other subject- but that is what my memory tells me.
Good luck,
