Good to know
Why range matters as much as accuracy
The official Band 7 descriptor asks for “a variety of complex structures” with “frequent error-free sentences”, two separate demands. A grammatically perfect essay written entirely in short simple sentences cannot score 7 on GRA, because nothing above Band 6 is demonstrated. Proofreading tools are structurally blind to this: they can only subtract errors, never tell you which structures are missing. The range notes in this checker report what an examiner would notice: whether relative clauses, conditionals, passives, and concession clauses actually appear in your writing.
From correction to permanent fix
Every flagged error carries the rule behind it and, where one exists, a link into the grammar library: articles errors point to the articles lesson, comma splices to the run-on sentences lesson. Fixing the same mistake in text after text is proofreading; studying the rule once and drilling it until it's automatic is learning. That loop (check, learn, practise, re-check) is what moves a band score, and it's the loop this tool is built around.
Speaking transcripts work too
GRA is also 25% of your Speaking score, and the descriptors are nearly identical. If you record your answers to practice questions, paste the transcript here: tense drift in Part 2 stories, missing subordination in Part 3 opinions, and embedded-question word order are the three patterns that most often cap speaking grammar at Band 6, and all three show up clearly in transcript checks.
