Level 1 Diagnostics - Level 1 Diagnostics is based on Dr. Steven Helschien’s dedication to preventive medicine and his theory that most of medicine is set up so that health professionals are like life guards and try to save patients who are drowning, rather than teaching them to swim. His new Level 1 testing is the most comprehensive and earliest cardiovascular testing available. This is how it compares to the other three levels of testing.

I took the GRE twice and had almost identical scores. If my memory served me right, I did not encounter any questions on the test that this book had. My advice to anyone preparing for GRE is to use actual math books.
This is an excellent cutting mat that is very self-healing. I keep it on my workbench, and it has been impervious to many different kinds of spills and spatters. The measuring increments marked on the mat make square cuts very easy and quick. It has protected my workbench from many accidental knife and exacto-knife cuts. Even with heavy pressure I have not cut all the way through the mat. Even if you are not a crafter, I recommend this for any workbench.
As a professional Biology tutor who has tutored over 20 students for the SAT II Biology exam, I highly recommend this book. Yes, it can be dense. Yes, the questions are difficult. However, the book has good explanations for the practice tests in the back of the book. I find the questions to be challenging but fair, and more accurate than the other options available. More importantly, the information presented in the book is more accurate than any of the other books that I have worked with (including Barron's and Princeton Review). There are a couple errors here and there that I have found (for example, one diagram shows human cells as tetraploid after DNA replication which is just wrong), but I have found many more mistakes in other books.
