Hi Dave
Cheating does not help, employers and other employees find that you do not meet the standard, new opportunities are often based on reputation.
That said it can be hard to find legitimate material if you just search the web.
Measureup.com provide practice tests approved by Microsoft and should do the job.
If you buy the Microsoft Training Guide (book not eBook) you get some different Measureup tests as part of the package, so this is a good option, my memory of this book is that it covered the requirements well.
Both these sources link to the MSDN if you ask for an explantion, enabling you to easily revise unfamiliar material.
If my memory is right the exam expires at the end of June 2011. By this I mean you can no longer take the exam. However once you have earned a qualification you do not lose it. 70-536 which is required for the MCTS does not expire at the
same time as is required for the 3.5 qualifications as well.
Hope this helps, and good luck,
Ozzy Geoff
