Worms? Where'd that come from? I think Dynamik asked if you were worn out, not wormed out.
Anywho, you were only like 3-4 questions away from a pass. You'll get it next time. I'd suggest you setup your lab to include at least 2 forests with a domain or two underneath them. Practice creating trusts, UPN's, Sites, GPO's, Maybe publish and assign some .MSI packages and all that jazz.
