Computer-Delivered vs Paper-Based IELTS

Since 2018, IELTS has been available in a computer-delivered format alongside the traditional paper-based test. Both formats are valid and produce the same qualification, but the experience is different. This lesson helps you decide which format suits you best and how to prepare for each.

Listening: Key Differences

Paper-Based Listening

Aspect	Detail
Audio delivery	Played through speakers in the room
During the test	Write answers on the question paper as you listen
Transfer time	10 minutes at the end to transfer answers to the official answer sheet
Answer format	Handwritten on a printed answer sheet

Computer-Delivered Listening

Aspect	Detail
Audio delivery	Played through individual headphones (you control the volume)
During the test	Type answers directly into the on-screen answer fields
Transfer time	2 minutes only (to review and finalise)
Answer format	Typed into text fields on screen

Which Is Better for Listening?

Advantage	Paper-Based	Computer-Delivered
Transfer time	10 minutes to check and correct answers	Only 2 minutes — much less review time
Audio quality	Room speakers — can be affected by acoustics	Headphones — clearer, individual volume control
Writing answers	Can write quickly without looking at the paper	Must type accurately; unfamiliar keyboards can slow you down
Noise isolation	Can hear other candidates' movements	Headphones provide some isolation

Strategy for Band 7+: If you rely heavily on the 10-minute transfer time to check spelling and correct answers, the paper-based test may be safer. If you have good typing speed and prefer headphone audio quality, computer-delivered is often better. The reduced transfer time on computer means you must enter answers as you listen — do not plan to write them later.

Reading: Key Differences

Paper-Based Reading

Aspect	Detail
Text presentation	Printed in a booklet — you can annotate, underline, circle key words
Questions	Printed alongside the passages
Answers	Written on a separate answer sheet
Navigation	Flip pages to move between the passage and questions

Computer-Delivered Reading

Aspect	Detail
Text presentation	Displayed on screen — split screen with passage on one side and questions on the other
Questions	Displayed alongside the passage on a split screen
Answers	Typed or selected (radio buttons, drag-and-drop) on screen
Navigation	Scroll within the passage; click between question groups
Highlighting	You can highlight text on screen (similar to paper annotation)

Which Is Better for Reading?

Advantage	Paper-Based	Computer-Delivered
Annotation	Natural — circle, underline, write notes in margins	Limited — can highlight but cannot write notes next to the text
Overview	Can see the whole passage at a glance by spreading pages	Must scroll — harder to get an overview of the whole text
Question navigation	Flip between pages	Click between question groups; split screen shows passage and questions simultaneously
Answer transfer	Must transfer answers from question paper to answer sheet (takes time, risk of errors)	Answers entered directly — no transfer needed

Strategy for Band 7+: Many candidates find paper-based Reading easier because they can physically interact with the text. However, the computer format eliminates the answer-transfer step, which can save 5–7 minutes. If you are comfortable reading on screen, the computer format is often more time-efficient.

Writing: Key Differences

This is where the two formats differ most significantly in terms of candidate experience.

Paper-Based Writing

Aspect	Detail
Writing method	Handwrite with a pencil on ruled paper
Word count	You must count words manually (or estimate)
Editing	Cross out and rewrite — can look messy
Planning	Write notes on the question paper
Legibility	Your handwriting must be legible to the examiner
