Grammar is only one part of a Cambridge writing response. The checker reads the complete task and draft together, using OpenAI's GPT-5.1 High Reasoning model to consider purpose, reader, register, language control, and the development of ideas. A phrase that suits a formal report may be wrong for an informal email, even when the grammar is correct. The analysis follows those choices through the response and explains them inside the four criterion report. You can inspect the evidence, decide whether the judgement fits your intention, and revise the passage that caused the problem. Model outputs can still be wrong, and the practice estimate is not an official result. The value is a contextual second reading that makes its revision points visible enough for you to challenge and use.
