It may seem innocent at first but once you use it makes you lose your $#*!. I was using this for the first time in school and I already hate it. They make you learn all these new things you don't need to learn. One time I finished a lesson and then it took me to $#*!ing Algebra. And that time was at the beginning of sixth grade. They added something new so when you're having trouble with a lesson, they'll let you move on. I like how they added that but sometimes they still give you harder lessons. Every $#*!ing kid hates this. Even most of the teachers hate it. I hope this can be replaced by some other learning program 'cause I'm pulling my hair out because of this thing.
