I like the little hat box that came with the gift card, it was fun to give instead of just a gift card in a graduation card.

I have a young Mexican man working for me doing yard work.  He wants to go into the military, but missed the entrance test by one point due to not being proficient in Algebra.  I ordered this book and gave it to him so he could study and pass the test.  He is doing really well in his studies and should pass the test now.

To know that no matter how hard the test you are given, you have the tools in love and joy to succeed. I bought one to for my family and one for my wife's uncle to hopefully help him.

It was a gift to my sister and was told that it was a big help to her while trying to doze off on the plane.  Based on her answer, I would have to say that it served its purpose.
