Hi
I have had my 270 exam booked for about 6 weeks,  and will be taking it in 14 days time.
I read an ebook for about 4 weeks on windows xp professional and recently completed it.
Now I have started taking the free online practise questions but, I find the practise questions on this site are alot easier than the ones on different sites. I find myself constantly scoring high on this site with a large understanding of each question and answer on this site, although when using practise questions from external sites, I find some of the questions very difficult, and hard to understand and that some of the material wasn't even covered in the ebook.
I am certain that the ebook wasn't a bogus and that it was directed for this exam.
for example:
You administer a Windows 2000 network for your company. You are planning to deploy Windows XP Professional on multiple computers simultaneously. After installation, how can you transfer multiple users’ states to the computers running Windows XP Professional?
A. This is not possible.
B. Use the System Preparation Tool.
C. Use the Files and Settings Transfer Wizard.
D. Use the Scanstate and Loadstate command-line tools.
Answer: D
I'm not aware of Scanstate and Loadstate and it wasn't mentioned within the study guide  

Any tips considering I am so close to the real exam?
cheers
edit: I also have transcender for 70-270.
