Why this happens to high school students
Safe, short sentences keep errors low but cap the range score. Grammatical Range and Accuracy asks for a mix of structures, and accurate complex sentences are one of the clearest markers of Band 7.
Why this affects high school students: essays at school are marked for content, so grammar and cohesion are less practised.
Simple sentences dominate and complex ones are error-prone.
A strength to build on: Younger learners can build good writing habits and improve steadily with regular practice.
Fix it in four steps
- Pick three structures you can write accurately: a relative clause, an although-clause and a conditional.
- Include at least one in each body paragraph.
- Combine two short sentences with a conjunction or a relative clause.
- Read each complex sentence aloud to check it is clear.
Before and after
Before
Cities are crowded. Cities have pollution. People still move there.
After
Although cities are crowded and polluted, people still move there for work.
Ten-minute drill: Take five simple sentences and combine each into one complex sentence in two different ways, then choose the clearer one.
