A quarter of your Writing band is Grammatical Range & Accuracy. These drills train the two halves of it separately: range — complex structures you can actually control — and accuracy, the error-free sentence runs Band 7 demands.
What the examiner reads for
Grammatical Range & Accuracy is 25% of your Writing band.
Spot the small, repeated slips — subject–verb agreement, articles, plurals, prepositions — that keep otherwise good essays stuck at Band 6.5.
Start the drill →Build relative clauses and subordination that survive contact with the exam — range only counts when the structure finishes error-free.
Start the drill →Conditionals, Task 1 passives and tense consistency — the timeline errors that surface when you write at exam speed.
Start the drill →Comma splices, fragments, semicolon use and dangling modifiers — the punctuation-level errors that separate 7 from 7.5+.
Start the drill →Understanding the criterion
Grammatical Range & Accuracy is 25% of your Writing band, and it is the criterion candidates misread most. The examiner is not counting big structures; they are reading for control — how many of your sentences are error-free, and whether your complex forms stay correct when you attempt them. A Band 6.5 script is understood despite errors; a Band 7 script produces frequent error-free sentences across a range of structures. These drills isolate the specific failures that hold scripts under 7: agreement slips, article errors, tense drift, and the comma splices that turn two correct sentences into one wrong one.
When a drill feels easy, write a full essay and see whether GRA holds up under exam pressure.
