Can the same letter be used twice in list selection?

Only if the instructions say so—most tasks use each option once. Read the rubric line before you start.

Should I read all options before locating?

Skim the list once for scope, then locate proof for one stem at a time. Do not hunt keywords across options in random order.

Why do almost-correct options feel right?

Examiners build overlap on topic words while breaking one constraint—time, agent, degree, or exclusivity.

Paragraph–Heading Mismatch Traps in IELTS Reading: When Headings Fit the Wrong Paragraph

Matching Headings · Border checks · May 2026

Direct answer

A paragraph–heading mismatch happens when the heading matches a slice of the paragraph—or an adjacent paragraph—better than the whole unit. You lock a letter because one sentence echoes the heading, while the paragraph's dominant function is different. Neighbor paragraphs steal headings when you skip border checks. Fix by testing whether every sentence in the paragraph lives under the heading's claim.

Why mismatches feel correct

Headings are paragraph-level contracts. A single vivid sentence can fake a match—see matching headings trap patterns and advanced Reading traps.

Sentence trap One sentence matches; the paragraph does not

Neighbor trap Heading fits paragraph above or below

Split trap Two short paragraphs share one theme; one heading spans both

Trap patterns that repeat every paper

Pattern	What you do	Correct check
Lock on first echo	Assign heading after one keyword hit	Test every sentence under the heading
Skip border read	Never compare paragraph N with N±1	Compare last line of previous para + first line of next
Function skip	Never label paragraph move (define/contrast/cause)	Heading must match move, not topic words

Verification loop under time

1. Stem underline

Circle the constraint: who, when, maximum, cause vs effect.

2. Proof phrase

Point to words that make the option true; if you cannot, reject it.

3. Cross-off discipline

Mark used letters immediately—see trap recognition speed.

4. Timed sets

One passage, list block only, 8-minute cap—then review with best AI IELTS tools.

Key takeaways

Mismatch errors are paragraph-level, not word-level.
One-sentence matches are the main Band 6 leak.
Border checks catch neighbor steals.
Tag function before you read the heading list.
