I sat for REG yesterday.  Whoo hoo!  I used the Wiley online test bank for most of the sims (plus about 2000 MCQ's) and supplemented with the ones in the Wiley book.  Some of them were simpler than the actual exam and some were a lot more detailed - not very helpful information to pass along, only to make the point that it's not really very consistent.  I also used the Bisk ones and they were about the same. 

I had read elsewhere that the Wiley sims were much easier than the actual exam sims, but I disagree. 

FWIW!
