The Binary Filter Protocol — 68% of Band 6.5 candidates lose critical marks on TFNG by using intuition instead of verification. Master the Subject + Claim method.
"When we write IELTS questions, we are not looking for your interpretation. We are testing your ability to verify logical equivalents. During calibration sessions, if a question requires reading between the lines, we reject it. The answer is always mathematically present in the text."

Stop guessing between False and Not Given — switch from intuition to mathematical verification.
VISUAL FRAMEWORK
You are in the exam room. You have 18 minutes left. You reach questions 21-26. You find the keyword. You read the sentence. You pause. Is it False or Not Given? That hesitation costs you 45 seconds per question.
In the marking room, we see the result: 68% of candidates stuck at Band 6.5 lose their critical marks here. They treat TFNG as a comprehension test. It isn't.
If you are guessing between False and Not Given, you are using intuition. To hit Band 7.5+, you must switch to binary verification.
Every TFNG question consists of a Subject (what we are talking about — names, dates, nouns) and a Claim (the controlling idea — verbs, adjectives, comparisons).
Once you isolate both parts, locate the Subject in the text, then run the Claim through the binary gate.
Not Given does not mean "I can't find it." Not Given means the Subject is there, but the specific Claim is missing.
| Feature | Band 6 Logic — The Guess | Examiner Logic — The Verification |
|---|---|---|
| Text | "Mr. Smith likes apples." | |
| Statement | "Mr. Smith prefers apples to oranges." | |
| Thinking | "He likes apples, so maybe he prefers them? Or maybe False because it doesn't mention oranges?" | Does the text contain a comparison? No. → NOT GIVEN. |
| Error | Uses outside knowledge and assumptions. | Checks only what is written in the text. |
| Feature | Band 6.0 Process | Band 8.0 Process |
|---|---|---|
| Focus | Reads the whole sentence, sees "warfare," gets confused by "previously assumed." | Isolates the claim: Did they find evidence of battle? |
| Keyword Match | Matches "excavation" and "warfare." | Matches "warfare" but notes the modifier "previously assumed." |
| Reasoning | "It mentions warfare, but says it was flooding. So it's False? Or maybe they found weapons?" | The text says warfare was "assumed" (past theory), but the evidence points to flooding. |
| Decision | Hesitant False (often changes to True). | Confident FALSE. The text contradicts that battle evidence was the cause. |
Run the filter — your verdict?
Apply the Subject + Claim method to three statements. Do not use outside knowledge.
"The 'Mozart Effect' — the theory that listening to classical music improves cognitive function — has been widely debated. A 2015 meta-analysis of 40 studies found that while listening to music elevates mood and arousal, which can temporarily boost performance on spatial tasks, there is no evidence of a permanent increase in IQ."

Run the filter — your verdict?
"If the text says 'The project might finish early,' and the statement says 'The project will finish early' — that is False. Certainty contradicts possibility. Watch for qualifiers like all, some, mainly, often, always."

Six rules to screenshot before your exam.
Band 7 candidates fall here because they overthink. Not Given means the Subject is present but the specific Claim is absent. Students try to "reason it out" instead of running the binary gate. The rule is simple: if the Claim is not in the text, stop and mark Not Given.
False = the text directly contradicts the statement (antonyms, opposite facts). Not Given = the text does not contain the information needed. If you cannot verify the Claim from the text alone, it is Not Given.
IELTS Reading tests verification ability, not general knowledge. If the text says "The sky is green" and the question asks "Is the sky green?", the answer is TRUE based on the text — even though you know the sky is blue. Outside knowledge = automatic fail.
The 60-Second Rule: If you haven't found the answer in 60 seconds, guess and move on. The easy marks count the same as the hard ones. Come back later if you have time.
Train speed on the binary gate. Read the statement. Find the Subject in the text. Check the Claim. Decide. 45 seconds max per question — that is your exam pace.
Recommended time allocation per TFNG question set. The 45-second ceiling prevents one question from destroying your entire passage score.
