Completion tasks look straightforward because you often write only one or two words. The difficulty is precision: the answer must fit the meaning, grammar and instruction limit at the same time.
Read the word limit first
Instructions such as “NO MORE THAN TWO WORDS AND/OR A NUMBER” are part of the question. A correct idea written with too many words can still lose the mark.
Predict the grammar before searching
Look at the gap and decide whether you need a noun, number, adjective, verb form or phrase. Grammar does not give you the answer, but it narrows the possibilities and helps you reject evidence that cannot fit.
Use the surrounding text to predict meaning
Ask what kind of information logically belongs in the gap: a cause, location, measurement, stage, material or result. Then search for that idea in the passage.
Expect paraphrase around the answer
The words surrounding a gap often paraphrase the passage. The actual answer may appear unchanged in the source text, but the clue around it can be expressed differently.
Use sequence when the task follows passage order
Many completion tasks follow the same order as the source information. Once you find one answer, the next is often further down the passage. This saves time and reduces random scanning.
Review fit, spelling and plurality
Put the answer back into the sentence or table mentally. Does it make grammatical and logical sense? Check spelling and singular/plural forms before moving on.
Frequently asked questions
Can I change the word from the passage?
When the task requires words from the text, use the exact form needed within the stated word limit unless the instructions say otherwise.
Do completion answers come in order?
Often yes, especially sentence and summary-style tasks, but always understand the specific question format rather than assuming every matching task follows order.
What should I do if two words seem possible?
Use grammar, meaning, word limit and the precise passage evidence together. IELTS questions are designed to have a defensible answer within the instructions.
