One star for what? – 1800 English Grammar Questions (Grammar In Use) - Free English language exercises for testing, learning, speaking, reading Review

Why are there grammar errors in the questions? Now, I know it’s English (not American) Grammar, but these errors are still errors in English grammar. It just seems like a cheaply-made app. Oh, and after I finished my first quiz, a pop-up notice said I answered 0/20 questions. It’s just a bad app. By the way, the app isn’t free. These developers are collecting money by way of advertisements. Just delete or skip this app.
