Its as if some one sat at their desk and thought "how could i ruin some ones life and academic career today?" this thing is a piece of garbage if you get something it just says which question is wrong and wont even try and help you. The explanations are worse because it goes through the whole problem instead of actually telling you what you did wrong so you have to look through the entire thing in order to understand. Plus i have to do 20 OF THESE kids have problems doing 10. Plus when says i'm wrong i get mad which makes me worse at math. This program is a piece of absolute trash. DO NOT GET FOR SCHOOLS.
