Complex vs Compound Sentences: Building Band 8+ Grammatical Range

How to use subordinating conjunctions and relative clauses to demonstrate grammatical complexity.

Practice Complex Clauses
## Grammatical Range & Accuracy (GRA) Criteria To score Band 7 or higher in GRA, candidates must produce *'a variety of complex structures with frequent error-free sentences'*. ### Sentence Types Breakdown: 1. **Compound Sentences (FANBOYS)**: Two independent clauses connected by a coordinating conjunction (*For, And, Nor, But, Or, Yet, So*). - *Electric vehicles are cleaner, **but** upfront purchase costs remain substantial.* 2. **Complex Sentences (Subordination)**: An independent clause paired with a dependent subordinate clause (*Although, Whereas, While, Because, Since, Unless, Provided that*). - * **Although** initial capital outlays for solar panels remain substantial, the long-term operational savings render renewable energy highly viable.* 3. **Complex Sentences (Relative Clauses)**: - *Metropolitan centers **that prioritize public transit** experience marked reductions in carbon emissions.*
5 Common IELTS Mistakes & Side-by-Side Corrections:
Common Candidate Mistake:

"Renewable energy is clean but it is expensive so governments must help."

Band 8+ Correct Form:

"Although renewable energy requires substantial initial expenditure, government subsidies can accelerate public adoption."

Why: Replaces repetitive coordinate linkers ('but... so...') with a sophisticated concessive complex clause.
Common Candidate Mistake:

"Because technology is advancing fast. Therefore jobs are changing."

Band 8+ Correct Form:

"Because technology is advancing rapidly, traditional employment structures are undergoing profound transformations."

Why: Never use 'Because' and 'Therefore' in the same sentence; 'Because' already establishes the subordinate relationship.
Common Candidate Mistake:

"Cities have many cars, which it causes pollution."

Band 8+ Correct Form:

"Cities have numerous vehicles, which causes severe air pollution."

Why: In a relative clause with 'which', do not include the redundant object pronoun 'it'.
Common Candidate Mistake:

"Despite of having high costs, many consumers buy electric cars."

Band 8+ Correct Form:

"Despite having high costs, many consumers purchase electric vehicles."

Why: 'Despite' is a preposition taking a gerund directly without 'of'. ('In spite of' uses 'of').
Common Candidate Mistake:

"The university offered new scholarships, and students applied for them, and enrollment increased."

Band 8+ Correct Form:

"When the university introduced new scholarship programs, student applications surged, precipitating an increase in overall enrollment."

Why: Eliminates stringy 'and... and' coordination in favor of temporal subordination and participle clauses.
