Thanks for taking the time to post! Here's to wishing you all the luck you need to get past this sucker!
I've had a look at Gregg's design practice and will take a closer look once I finish reading the vSphere Design book. I see where your coming from about the breadth of the material, I could be reading/labbing for years and still not feel ready enough - just because I dont know what to expect. I have vouchers to use for this test, so that helps pay for part of the exam fees. So the hit on the hip pocket shouldnt be too bad, in case I fail one or two shots at this. But I aint giving up, whether I fail once/twice/n times.
Once again, good luck on Tuesday! Please do let us know how you go and what you think of the test.
