The Ultimate Math Refresher for GRE, GMAT, and SAT
While viewing the data that was presented by your company, I decided to order materials to prepare for the GMAT.  I received the study guides of which one was the math refresher workbook.  After being out of the college enviornment for over 20 years, I was amazed at how little I had retained.  But, I can say without reservation the information in the math refresher workbook was vital in my grasping the materials for the GMAT.  The information in the actual GMAT booklet proved invaluable.  Thanks for being a provider of information that was crucial to my understanding of the GMAT.  --David F. Wagoner, Sr.
