NOTE: This is 1 of 4 versions of the same product.
This version is text or voice with only NICE comments. Example: You miss a problem - it will put out a message like "Don't worry about it. I am sure you will get the next one." or "I am sure it was a hard one."
If you would like one that has mean comments or talks to you then try out one of the other versions.
This product will do two things.
1) Teach you how to work problems involving Permutations and Combinations.
2) Test you over the material.
