I passed 70-293 with a 837 and was not able to answer any sims. When I took 70-294 yesterday I felt the exact same-good on questions and could not answer sims well at all. Well, I failed with a 497!!

How is that possible, do they grade it differently. The sims killed me and I really don't have any systems set up at my house to simulate a network, I can't play with GPO"s, OU's, etc.
I did not use the CBT nuggets from my work for this exam so that kinda hurt me, I just studied the practice questions from Microsoft. Does anyone know where I can buy a CD that has simulations so I can practice that way? I rember I had one for CCNA and it was like you were on a full blown network.
I have just studied from a book for all my certs, I have taken no classes, just winged it:)
