Excellent!!!!
Excellent!!!! I am receiving the online version and it is really very good. The explanation of the teacher and the examples that he gives in each section make it easy for you to understand each topic. The tips he provides are super for calculations with the T. I have laughed a lot with the example he gave us of the child and Dad; the child is above the father's shoulders and the father is below the shoulders.
