Grammar can be hard to teach, but with Grammar Up, it doesn’t have to be. Different sections of the app are devoted to different parts of speech, like adjectives, adverbs, causative verbs, conditionals and many more.
Each section has the technical definition of the part of speech followed by a test for students to take in order to “Grammar Up” and reach the next level.
