Here's what confuses most students: both Yes/No/Not Given (YNNG) and True/False/Not Given (TFNG) questions show up on IELTS Reading, and they look almost identical. They're not. The difference between YNNG and TFNG is subtle but real, and it costs you points when you miss it.
You need to understand this distinction now, before you grind through 50 practice tests and lock in bad habits.
It all comes down to what the question is asking you to evaluate.
Yes/No/Not Given questions ask whether you agree with a statement based on the author's opinion or claim. You're checking what the writer believes or asserts.
True/False/Not Given questions ask whether a statement matches factual information in the text. You're checking objective facts, not opinions.
Here's why this matters: the exact same sentence can produce different answers depending on how the question frames it.
Example passage: "The research team believes that climate change poses the greatest threat to global biodiversity. However, some economists argue that economic growth must take priority."
Question A (YNNG): "Do you agree that climate change poses the greatest threat?"
Answer: Yes. The author states this is what the team believes.
Question B (TFNG): "Climate change is the greatest threat to global biodiversity."
Answer: Not Given. We're told what the team believes, not given it as a fact.
Yes/No/Not Given questions ask you to evaluate claims and perspectives. You're deciding whether the passage backs up a particular viewpoint. This IELTS reading question type tests your ability to distinguish between what's stated, contradicted, or missing from the author's position.
Here's where most students slip up: they think "the passage mentions this" means "the passage agrees with this." Those are completely different things.
What doesn't work: You read "Remote work increases productivity" and answer "Yes" just because the passage mentions remote work. Stop. You need the passage to actually claim that remote work increases productivity.
What works: You search for sentences like "Studies show remote workers complete 25% more tasks" or "remote work is less productive than office settings." Only the first one supports a "Yes" answer.
True/False/Not Given questions test whether the passage contains factual information that matches your statement. You're not evaluating opinion here. You're checking facts. What does the text actually say happened, exists, or is true?
What doesn't work: The passage says "The Eiffel Tower was completed in 1889." You see the statement "The Eiffel Tower was built in the 19th century" and answer False because the wording is different. Wrong answer. The facts match.
What works: You extract the core fact (completed 1889) and check if the statement's meaning aligns with it. Yes, 1889 is the 19th century. Answer: True. You're matching meaning, not memorizing words.
Example 1: Claims vs Facts
Passage: "Some researchers claim that artificial intelligence will revolutionize medicine within 10 years, though others are skeptical."
Statement A (YNNG): "Artificial intelligence will revolutionize medicine within 10 years."
Answer: No. This is presented as one claim, not as something the author agrees with.
Statement B (TFNG): "Some researchers believe AI will revolutionize medicine within 10 years."
Answer: True. This matches the factual information provided.
Example 2: Negatives Matter
Passage: "Unlike previous models, the new smartphone does not require daily charging."
Statement A (YNNG): "The new smartphone requires daily charging."
Answer: No. The passage directly contradicts this.
Statement B (TFNG): "The new smartphone requires daily charging."
Answer: False. The passage states the opposite as a fact.
No and False sound similar, but they come from different question types. YNNG evaluates whether you agree with the author; TFNG evaluates whether facts match.
Example 3: Missing Information
Passage: "The company expanded into three European markets last year and plans to open offices in Asia next year."
Statement A (YNNG): "The company should expand into African markets."
Answer: Not Given. The author never expresses this opinion.
Statement B (TFNG): "The company operates in African markets."
Answer: Not Given. The passage only mentions European and future Asia markets.
The question stem tells you everything. Look for these patterns to distinguish between the two IELTS reading question types.
YNNG signals: "Do you agree...", "Does the author believe...", "Does the passage suggest...", "Is it stated...", "According to the passage..." These ask about opinions and claims.
TFNG signals: "The following statement is...", "Which of the following is true...", "According to the passage...", or a statement with no editorial language. These ask about facts.
Real numbers: Most IELTS Reading tests use YNNG questions more often than TFNG. You'll typically see 10-15 YNNG questions and 5-10 TFNG questions in a full Reading test. YNNG appears in roughly 60% of tests. Both test your comprehension, but YNNG is your higher priority.
Mistake 1: Using outside knowledge instead of the text.
You know the Earth orbits the Sun. But if the passage says "The Sun orbits the Earth" and you get a TFNG question asking "The Sun orbits the Earth," the answer is True. Your job is comprehension, not facts. Base every answer on what the text says.
Mistake 2: Confusing related information with matching information.
The passage talks about coffee prices rising. The statement says "Coffee consumption is increasing." These topics connect, but they're not the same claim. That's Not Given, not Yes or True. Be specific about what the text actually says.
Mistake 3: Treating Not Given like a last resort.
Some students assume every answer is Yes or No, True or False, then stretch to find a connection. Stop. If the information isn't there, it's Not Given. Expect this answer roughly 25-30% of the time across a full Reading test. It's normal.
Mistake 4: Missing qualifiers and negatives.
Passage: "The majority of participants completed the survey within one week." Statement: "All participants completed the survey within one week." This is False, not True. The passage says "majority," not "all." One word changes everything.
Before answering, identify what's being asked. Are you evaluating an opinion or a fact?
For YNNG: Search for the author's position or claim. Does the passage support it, contradict it, or not mention it? Underline the supporting sentence in the text.
For TFNG: Search for factual statements that match your test statement. Does the information align? Watch for qualifiers, negatives, and specific details that could flip your answer from True to False.
Here's the practical process: read the statement, underline key words, find the relevant paragraph, extract the relevant sentence, check if it supports (Yes/True), contradicts (No/False), or ignores (Not Given) what you're testing. Understanding how to use skimming and scanning techniques will help you locate these key sentences faster under time pressure.
Time reality: You get 60 minutes for three passages and 40 questions. That's roughly 20 minutes per passage. Don't get stuck on one question. Mark it uncertain and move on. If you have 5 minutes left, circle back to it.
IELTS Reading tests your ability to locate and process information accurately. Missing the difference between YNNG and TFNG hurts your Task Response band, one of the core descriptors they grade.
The official IELTS band descriptors say Band 7 readers "locate main ideas efficiently" and distinguish between explicit and implicit information. That's exactly what these question types assess. Miss this distinction, and Band 7 becomes very hard to reach. Band 6 readers often confuse opinion with fact, while Band 7+ consistently identify which is which.
A full IELTS Reading test includes 10-15 YNNG questions and 5-10 TFNG questions. That's 15-25 points of the 40 total. You can't afford to misunderstand these.
Understanding the difference between YNNG and TFNG in theory is one thing. Recognizing it under test conditions is another. The best way to lock this in is consistent practice on real passages. Use a band score calculator to track your accuracy on each question type separately, so you know which one needs more work.
Start by working through passages where you deliberately mark which type each question is before you answer. This forces your brain to shift mental gears. After 20-30 questions, the distinction becomes automatic.
