GRE preparation by Molitoris_J.J._The_GRE_physics_test

Does anyone prepare the GRE physics test by Molitoris_J.J._The_GRE_physics_test_preparation?
I found that the 4 tests in the end of this book is quiet hard. I always got low score and I sometime realize that I just first saw some formula in Physics in this book. In some questions, there are a bit tough calculation like ln or exponential or complicated multiplication. Does anyone fell like me? and how do I prepare for the test efficiently?

The Molitoris book is a horrendously inaccurate representation of the GRE Physics Test. The problems are uncharacteristically difficult and many calculations are too difficult to do with a paper and pencil in 1 minutes time.

You prep time is better spent reviewing the actual released Physics GRE questions from ETS. These are actual GRE questions from previous years. Also, I have heard there are usually several questions from the practice tests which are reused every year.

The four released tests can be found here, among other websites:

These questions should be the focus of your prep efforts, in my opinion. Don't bother with the Molitoris book. It isn't a good representative and is full of errors. Although, its review of physics is somewhat useful, the fake exams aren't.

Thanks a lot G01.
I think I will find the way in the actual practice test from ETS.
