Complex sentences that are actually correct

Coaching centres often tell students: "Use complex sentences for a high grammar score." So students build long, complicated sentences. But many of these sentences contain errors, and errors lower the score. Band 7 needs a range of complex structures and frequent error-free sentences. Range without accuracy doesn't work.

Why this matters

Grammatical Range and Accuracy rewards both variety and correctness. A student who uses five accurate complex sentences usually scores higher than one who uses fifteen with errors. The goal is control.

Six structures worth mastering

1. Relative clauses

Defining (no commas): "Students who work part-time often have less time to study."
Non-defining (with commas): "Dhaka, which is home to millions of people, faces serious traffic problems."

Use who for people, which for things, whose for possession, where for places.

2. Conditionals

First: "If governments invest in public transport, traffic will decrease."
Second: "If university were free, more students would apply."

3. Concession

"Although online learning is flexible, it can feel isolating."
"Despite its benefits, online learning can feel isolating."
"While some people prefer cities, others value the peace of village life."

4. Cause and result

"Because fuel prices rose, many people switched to public transport."
"Because of rising fuel prices, many people switched..."
"Fuel prices rose, which led to a fall in car use."

5. Participle clauses

"Having finished their studies, many graduates return home."
"Faced with rising costs, families are cutting back on spending."

6. Emphasis structures

"What matters most is the quality of teaching."
"It is the cost, not the distance, that stops many students from studying abroad."

The most common errors

Wrong	Right
Although it is expensive, but it is useful.	Although it is expensive, it is useful.
Despite of the cost, ...	Despite the cost, ...
Despite it is expensive, ...	Despite being expensive, ... / Although it is expensive, ...
The teacher which helped me ...	The teacher who helped me ...
If I will get a scholarship, I will study abroad.	If I get a scholarship, I will study abroad.
Because of the traffic is bad, ...	Because the traffic is bad, ...

Although and but never go together in one sentence. This is one of the most common errors in our writing.

Range with control

In each essay, aim to use three or four different complex structures correctly. You don't need all six every time. Mix them with clear simple sentences. A short, simple sentence after a long one is good style.

Try it yourself

Combine each pair using the structure in brackets.

Many students study abroad. They often face culture shock. (relative clause)
The course is expensive. It is very popular. (concession)
The government built a new metro. Traffic decreased. (result)

Sample answers:

Many students who study abroad face culture shock.
Although the course is expensive, it is very popular.
The government built a new metro, which led to a decrease in traffic.

Honest note

If you're not sure a complex sentence is correct, split it into two simple ones. A correct simple sentence never lowers your score. An incorrect complex one does.
