Clear and precise writing is essential, especially for exams like IELTS. Even small mistakes can confuse readers and lower your score. Here are some common sentence errors and how to fix them.

1. Using ‘Who’ and ‘Which’ Incorrectly

Incorrect Example:
The students, which are studying at the institute, performed well in the exam.

Why It’s Wrong:
The word “which” refers to “students,” which is incorrect because “which” is meant for things, not people.

Correct Version:
The students who are studying at the institute performed well in the exam.

Why It Works:
Using “who” correctly refers to the students, making the sentence clear and grammatically accurate.

2. Phrases That Don’t Make Sense

Incorrect Example:
After finishing the assignment, the results were disappointing.

Why It’s Wrong:
The phrase “After finishing the assignment” seems to describe “the results,” but results cannot complete an action.

Correct Version:
After finishing the assignment, the student found the results disappointing.

Why It Works:
This version clearly shows that the student completed the assignment, making the sentence logical.

3. Mistakes in ‘If’ Sentences

Incorrect Example:
If students will practice regularly, they will improve their scores.

Why It’s Wrong:
Using “will” in the “if” clause is incorrect in conditional sentences.

Correct Version:
If students practice regularly, they will improve their scores.

Why It Works:
This follows the first conditional structure: “If + present simple, … will + verb,” used to describe real and possible future situations.

4. Incomplete Sentences

Incorrect Example:
Because the survey included many participants. The conclusions might not be accurate.

Why It’s Wrong:
The first part is a sentence fragment and cannot stand alone.

Correct Version:
Because the survey included many participants, the conclusions might not be accurate.

Why It Works:
Combining the two parts forms a complete and grammatically correct sentence.

Final Tip:

Always check your sentences for clarity, subject agreement, and proper grammar. Small adjustments can significantly improve readability and scores, particularly for IELTS writing tasks.
