Form Completion (Part 1)
Word limits · spelling alphabet · phone & address conventions · number-listening techniques · 11 practice exercises
Topic & Why It Matters
Form Completion is the standard opening question type for IELTS Listening Part 1. You listen to a conversation between two people — typically a customer enquiry, a booking, or a registration — and fill in missing details on a printed form: names, phone numbers, addresses, dates, prices, and similar factual information.
Part 1 is the easiest section of the test, yet many candidates drop marks here because they violate the word limit, mishear a spelling sequence, or write the uncorrected version of a self-corrected answer. Since every blank is worth one mark, even two mistakes here can cost half a band at the lower end of the scoring range.
If you find numbers slippery — phone digits flying past, dates blurring with prices, "thirteen" and "thirty" sounding identical — you are in the right chapter. Below you will find a dedicated number-listening toolkit, a confusion-pairs reference, a focused number mini-drill, and eleven full practice exercises covering every Part-1 booking scenario the test favours.
Knowledge Points
Number Listening Toolkit
Most Part-1 mistakes are number mistakes. Below are ten techniques that turn fuzzy number sounds into the right digits on your form. Each technique has its own trigger, a worked example, and a backup move for the moment you draw a blank.
1. The -teen / -ty stress trap
Listen for stress placement. "thir-TEEN" has the stress on the second syllable and a long /iː/ sound; "THIR-ty" has the stress on the first syllable and a short /i/ sound, with the final /-tee/ often weakened.
- "It opens at thirTEEN minutes past nine" → 13
- "The fee is THIRty pounds" → 30
- "Room fifTEEN" → 15 (long final sound)
- "Page FIFty" → 50 (clipped final sound)
Backup move: If you genuinely cannot hear it, use context. Ages 13–19 are teen years; round prices and quantities often end in 0. When two candidates are both plausible, listen for the speaker's confirmation repeat — they almost always restate the number.
2. Chunking phone numbers and codes
Native speakers never read 11 digits as one giant number. They group them into chunks of 3–4 separated by tiny pauses. Use those pauses to write each chunk immediately, then move on.
- "oh seven seven four one … double eight … nine six three" → 07741 88 963
- "oh two oh seven … nine four six … oh five eight eight" → 0207 946 0588
- "reference triple four, six oh two" → 444602
Backup move: When you hear "double" or "triple," write both/three digits in one go — do not write just one and hope to add the others on the repeat.
3. Decoding dates
British dates use ordinals + "of" + month: "the fourteenth of April." Notice the consonant clusters: "fourTH," "fifTH," "twelfTH" — these are voiceless and easy to miss. Write the day as a number (14), not the word.
- "the third of June" → 3 June or June 3
- "the twenty-first of August" → 21 August
- "the second of February — sorry, the twelfth" → 12 February (corrected)
Backup move: If the form already prints "_____ April," write only the day (14). If it prints the day, write only the month. Never duplicate.
4. Reading years correctly
Years 1000–1999 are read in two pairs (nineteen-eighty-five). Years 2000–2009 use 'two thousand and X' or 'twenty oh X.' From 2010 onwards, 'twenty fifteen' is the dominant form. Listen for the pair pattern; it locks the century.
- "nineteen ninety-eight" → 1998
- "two thousand and four" → 2004
- "twenty oh seven" → 2007
- "twenty twenty-five" → 2025
Backup move: A "born in" or "since" cue almost always precedes a year. Once you hear that cue, brace for a four-digit number.
5. Time formats
Three common forms: digital ("nine thirty" = 9:30), British analogue ("half past nine" = 9:30 — NOT 8:30), and "quarter" forms ("quarter past nine" = 9:15; "quarter to ten" = 9:45).
- "half past three" → 3:30
- "quarter to five" → 4:45
- "twenty to seven" → 6:40
- "a.m." = morning; "p.m." = afternoon/evening
Backup move: If the form has "____ a.m.," do not write "a.m." in the blank — it is already printed. Just write the digits.
6. Money: pounds, dollars, pence
"£15.50" can be read as "fifteen pounds fifty," "fifteen pounds and fifty pence," or "fifteen fifty." If the form prints "£," do not write the symbol; just write the number.
- "twelve ninety-nine" → 12.99
- "a pound fifty" → 1.50
- "thirty quid" (informal) → 30
- "two hundred and fifty pounds per night" → 250
Backup move: Watch for "per person / per night / per week." If the form says "£ ___ per night," write only the number — the unit is already printed.
7. Decimals and fractions
After the decimal point, digits are read individually: '3.14' = 'three point one four.' Fractions are vocabulary: 'a half' (½), 'a quarter' (¼), 'two thirds' (⅔). Hours can use either: 'two and a half hours' = 2.5 hours.
- "two point seven five metres" → 2.75
- "three and a half kilos" → 3.5 kg
- "a quarter of an hour" → 15 minutes
Backup move: Listen for the unit (metre, kilo, hour) immediately after the number — it confirms what type of measurement you are writing.
8. UK postcodes
Format: 1–2 letters + 1–2 digits, a space, 1 digit + 2 letters. e.g., SW1A 2AA. Speakers always read postcodes letter-by-letter and digit-by-digit, often with NATO clarifications: 'S for Sierra, W for Whiskey.'
- "S, W, one, A, two, A, A" → SW1A 2AA
- "M, K, four, five, eight, G, S" → MK45 8GS
- "E, C, two, M, six, X, H" → EC2M 6XH
Backup move: If you miss a letter, listen for the NATO clarifier ("E for Echo") — it always follows on a repeat.
9. Approximations and ranges
Speakers may soften numbers with "around," "roughly," "just over," "almost." Write the stated number. The softener is filler — it does not change the answer unless the speaker corrects to a different value.
- "around fifty pounds" → 50
- "just over two hundred" → 200
- "almost a thousand visitors" → 1000
Backup move: Only override the stated number if the speaker explicitly corrects: "around fifty — actually, fifty-five." Then write 55.
10. The self-correction signal
Numbers are the most commonly self-corrected items in Part 1. Train your ear for the trigger words: "sorry," "actually," "I mean," "no, wait," "make that." The number AFTER one of these words is the answer.
- "It's the sixth — sorry, the sixteenth" → 16
- "Forty-five — actually, forty-five-fifty" → 45.50
- "Room 207 — no wait, 270" → 270
Backup move: Write the first number lightly in pencil. The instant you hear a trigger word, cross it out and write the new one. Never erase — you may need to compare.
Confusion Pairs — Quick Reference
These pairs cause the majority of wrong answers in IELTS Part 1. Memorise the discriminating cue so your ear knows what to grab onto.
| Pair | How to tell them apart |
|---|---|
| 13 / 30 | thir-TEEN (long, end-stressed) vs THIR-ty (short, front-stressed) |
| 14 / 40 | four-TEEN vs FOR-ty (note: no "u" sound in forty) |
| 15 / 50 | fif-TEEN vs FIF-ty |
| 16 / 60 | six-TEEN vs SIX-ty |
| 17 / 70 | seven-TEEN vs SEV-en-ty |
| 18 / 80 | eight-TEEN vs EIGH-ty |
| 19 / 90 | nine-TEEN vs NINE-ty |
| B / D / P | B for Bravo, D for Delta, P for Papa — all sound similar on phone |
| M / N | M for Mike (lips closed), N for November (tongue on teeth) |
| I / Y / E | I for India, Y for Yankee, E for Echo — note vowel quality |
| A / H / K / J | A for Alpha, H for Hotel, K for Kilo, J for Juliet |
| S / F / X | S for Sierra, F for Foxtrot, X for X-ray — all hiss sounds |
| G / J | G for Golf (hard g), J for Juliet (j sound) |
| C / Z | C for Charlie, Z (British "zed", American "zee") for Zulu |
Step-by-Step Strategy
Common Pitfalls
| Mistake | Corrective Rule |
|---|---|
| Writing too many words | Count every word: "credit card" = two words. If the limit is one word, write "card." |
| Confusing M and N | Listen for confirmation: "N for November" or "M for Mike." Lean on context when no cue is given. |
| Confusing -teen and -ty | Listen for stress placement, then verify with context. A monthly fee of 13 is unlikely; 30 is typical. Use the second mention if the speaker repeats. |
| Missing a self-correction | If the speaker says "the sixth — I mean the sixteenth," write 16, not 6. Always use the final version. |
| "Double" misread | "Double 4" = 44, not 4. Write both digits. Same rule for "treble/triple." |
| Copying pre-printed text | If the form shows "07741 ___," write only the missing digits. Rewriting 07741 wastes words. |
| Writing the symbol with the value | If the form prints "£" or "@" or "a.m.", do NOT repeat it in the blank. Write only the missing characters. |
| Half past confusion | "Half past three" = 3:30, NOT 2:30. In English, "half past X" means thirty minutes AFTER X. |
| Year written as two digits | Write 1998, not 98. Write 2025, not 25. IELTS forms expect the full four-digit year unless the blank explicitly shows "20__". |
Vocabulary Bank
| Expression / Convention | Usage Note |
|---|---|
| That's B for Bravo | Confirms the letter B |
| Double [digit] | Two consecutive identical digits, e.g. double 8 = 88 |
| Triple / treble [digit] | Three consecutive identical digits |
| Oh | The digit 0 in phone numbers and codes |
| Zero / nil | The digit 0 in temperatures, scores ("two-nil"), technical contexts |
| Can I take your name / number / postcode? | Signals the next blank is about to be answered |
| How do you spell that? | Spelling sequence follows immediately |
| Sorry, could you repeat that? | Answer will be said a second time — listen to the repeat |
| No, sorry — I meant … | Override: write the word AFTER this phrase |
| Actually, make that … | Override: write the corrected value |
| Let me read that back to you | Speaker is about to repeat the entire detail set — perfect for verification |
| The [ordinal] of [month] | Date format: 'the fourteenth of April' → 14 April |
| £ [number] per person / per night / per week | Price format in booking contexts |
| [Number] pounds [number] (pence) | "Fifteen pounds fifty" = £15.50 |
| Half past [hour] | 30 minutes after the hour ("half past 3" = 3:30) |
| Quarter past / Quarter to [hour] | Quarter past 9 = 9:15; quarter to 10 = 9:45 |
| [Number] a.m. / p.m. | a.m. = before noon; p.m. = noon onwards |
| Around / Roughly / Just over [number] | Softeners; write the stated number unless explicitly corrected |
| Per night / per person / per week / per session | Unit that follows a price — already on the form, do not rewrite |
| That's [digit group] [digit group] | Phone chunking: '0774 188 963' |
| Flat / Apartment [number] | British address: flat precedes street number |
| [Street name] Road / Street / Avenue / Lane | Common UK road-name endings |
| Postcode: [letters + digits + space + digit + letters] | UK postcode format, e.g. SW1A 2AA |
| Is that right? / Let me read that back. | Speaker is about to repeat — second chance to confirm |
| Got that / Perfect / Great | Blank is closed; next topic starting |
Practice — 11 Exercises + Number Mini-Drill
Instructions: For each exercise, play the audio once (as in the real test), complete the form, then click Check. Write NO MORE THAN ONE WORD AND/OR A NUMBER per blank. Replay only after checking, comparing against the script — your goal is to identify which number-listening technique would have caught the miss.
P1.Riverside Tours Booking
A customer calls a half-day city tour operator to make a booking. Standard opener covering name, phone, email, date, group size, time, dietary needs, and payment.
🎯 Technique focus: phone chunking with 'double', date + time
🧪 Number Mini-Drill — Isolated Transcription
No conversation, no context — just twelve short statements. The single best way to fix the "numbers fly past me" feeling is to drill them in isolation until the sound-to-digit mapping is automatic. Each item targets a specific trap: phone, year, price, half-past, -teen/-ty, ordinal date, postcode, decimal, quarter time, self-correction, triple, and one more teen test.
🎯 If you score under 9 / 12, re-run it before attempting the full practices below.

Self-Check
Answer these from memory before looking back. If you cannot answer all eight, re-read the relevant section.
- What does "double 4" mean in a phone number, and how many digits do you write?
- If the word limit is one word and/or a number, which is correct: (a) credit card, (b) card, (c) by card?
- A speaker says 'the sixth — no, sorry, the sixteenth.' What do you write?
- "Half past three" — write the time in 24-hour-style digits.
- Distinguish 'thirteen' and 'thirty' by stress: which is end-stressed?
- "Twenty fifteen" — write the year.
- You hear "fifteen pounds fifty". Write the price as it should appear on a form that prints "£".
- What is the digit form of 'a quarter to nine'?
Show answers
- (1) "Double 4" = 44. Write both digits.
- (2) (b) card — "credit card" is two words; "by card" adds an unnecessary preposition.
- (3) 16 — always write the corrected value after "sorry / actually / I mean".
- (4) 3:30 (half past X means thirty minutes AFTER X).
- (5) "thirteen" — end-stressed (thir-TEEN); "thirty" is front-stressed (THIR-ty).
- (6) 2015 — modern years are read as two pairs.
- (7) 15.50 — write only the digits; the £ symbol is already printed.
- (8) 8:45 — "quarter to" means fifteen minutes before the stated hour.
