The tool grades your writing, not you. Although you may be a Proficient user of English, if you answer a question in the Beginner workbooks, for example, it will be a good Beginner standard essay - a short essay, with no complex grammar, simple sentences, but with a good variety of vocabulary for Beginner. And one you write in Advanced will be Advanced standard. It is the writing that is given a grade. It is impossible, for example, to score C1 for a Beginner essay, because to score C1 you need to demonstrate a wide range of grammatical structures and functions and complex vocabulary and phraseology. You can’t do that in 30 words about your daily routines, for example. It is important to choose the workbook that is most suitable for you.
