Grammatical range and accuracy
Improve Grammatical Range and Accuracy: a mix of complex structures used accurately, and the most common errors to eliminate.
In this lesson you will
- Use a range of complex structures naturally
- Eliminate high-frequency errors
- Check your grammar efficiently
Learn
This criterion rewards range (a mix of simple and complex sentences) and accuracy (the proportion of error-free sentences). Both matter.
Useful complex structures: conditionals (If governments invested more, …), relative clauses (…, which means that…), passives (It is often argued that…), concession (Although…, …), participle clauses (Having considered both sides, …), comparatives (the more…, the more…).
Frequent errors: articles (the society ✗ → society), subject–verb agreement (people is ✗), countable/uncountable (informations ✗), comma splices, verb forms (can helps ✗), prepositions (discuss about ✗).
Check (3–5 minutes): read once for verbs (tense, agreement), once for articles and plurals, once for sentence boundaries.
Examples
- Conditional: If more people used public transport, congestion would fall.
- Relative: Many people move to cities, which puts pressure on housing.
- Concession: Although technology has benefits, it can also isolate people.
