Breaking Ground - the 70-290

So here I am, I've been working with Micrsoft products for years. Put in 
about 3 years with 2003 server and it time to hit the certification trail 
once again. (My MCP is quite dated). Took the class, read the books, been 
adminsitrating 03 server for quite a while. 

I've been taking the prep tests to test my knowledge. Wow, what I don't
know 
about server 03. There are literally hundreds of GPO's how can anyone 
realistically remember what all of them do. Is this to be taken seriously?

Most other aspects of the 290 test are ... well there, I'm reasonably 
confident. Geez, for those of you that have actually taken the test, tell
me, 
are the questions really going to be truly that obsure? ( I'm looking for
a 
little hope here!)
