What is Sentence Completion in IELTS Reading?
Sentence completion is an IELTS reading task where incomplete sentences are given, and you fill in the blanks using words or phrases directly from the passage. This tests your ability to locate relevant information and understand context.
In sentence completion, you read incomplete statements and find the exact words from the text that complete them correctly. Accuracy and finding the precise context are essential.
