Best in class

I dont know why are others are whining but I think the app is what it says in description. Why do people whine about what its not? Its practice tool people. Not teaching material. Its aim is to revise again and again the rules of the grammar that you have learned in school. If you want to learn the grammar rules, go a pick up a good book and come back to this app for revision and practice.
