How good are the Measure Up practice exams?

How good are the Measure Up practice exams that come with the Microsoft Self-Paced study book for 2008 R2? This weekend I am going to get the Transcender practice exams, but I am curious how others feel about the Measure Up practice tests. In the Configuring and Maintaining AD Objects section, I am getting mid-80's on the practice tests. I am feeling much more comfortable with the information, but wondered if the Measure Up practice tests are close to what I might experience with the real exam.
Thanks!
Thanks!

Many judge their skills off of practice tests and fail. Judge yourself based on your learning style. Mine is to make sure I can re-phrase 2008 topics in my own words, their general purpose, and what I would click in order to perform said task. Microsoft seems to be pushing a lot harder on the "hands on"/"know scenarios" knowledge of the tests.
You may learn something!

I am also reading a lot of Technet articles on the items I am studying at the time, but haven't been labbing as much lately. I'm working on a study schedule right now to get more lab time in because I know it's vital.
Thanks again!

I have also started going through Technet and printing out a lot of the material to add to my studies. Tt' amazing the level of information it provides.
