Hi, Congratulations for your AZ304. I failed mine by 640. And I'm bit disapointed. Cleared AZ303 before. These exams are clearly far difficult than many others. 
I have some short questions for you of you authorize me (and want to help me a bit  

 )
When you took the Exam the second time did you get the same set of questions ? 
How many questions did you get ? How many cases ?
Also I was supprised to get many tricky questions with AKS and ACI.  That was the case for you ?
Finally, what pratcice tests did you use ? Which ones are the best according to you ?
Many thanks.
