English unit

An English unit is a way that we measure how much we know about the English language. Just like we measure how heavy something is in pounds, or how tall something is in inches, an English unit measures how much we know about grammar, spelling, writing, and reading. It's like a big puzzle, and each unit is like one piece of that puzzle that we put together to help us become better at English. So when we finish all the units, we have a complete puzzle and we know a lot about the English language!
