Difference between paper based and computer based IELTS

Although the difference between paper based and computer based IELTS is a regularly asked question, the answer is within the question itself – the delivery method. One is delivered via a computer, and the other is through paper.

Understandably, the main information the people wanted to know was – if there was any difference in the exam structure, such as different types of questions, tasks, and so on. This article will give you a clear and precise answer to your questions.

Please, remember that this article is written for Bangladeshi test-takers in Bangladesh. The order in which the modules come in can be different in your country for both CDI and Paper-based IELTS.

Writing section

In a paper-based exam, you can use a pen or pencil based on the instruction from your test center. Usually, you use a pencil.

On the other hand, you need to type your answer on a computer in a computer-based exam. However, you will get a pencil and a piece of paper to take notes for the exam in CDI.


The listening section in CDI is shorter than the paper-based exam. In some cases, you do not get headphones in paper-based IELTS, but you get a pair of headphones in CDI. This is because you will not get the extra 10 minutes in the CDI listening.


In CDI, you get to sit for the speaking test on the same day as the other modules, although the order of the delivery of the modules can be different.


In the paper-based exam, you take your test in a large hall with many other examinees, but in CDI, the room is very small, and you can take the exam with only a few students. The environment is much more comfortable.


CDI gives your result within a week, but a paper-based exam needs two weeks to process your result.

More Availability

You can only have four IELTS tests in a paper-based version in a month. On the other hand, you can sit for a CDI more times than the paper-based IELTS.
