Easier to make corrections (copying and pasting is not allowed)
Timer to help you manage the time
Word counter in the writing part
Headphones for the listening (less distractions?)
A lot of centres have the speaking test on the same date as the rest of the exam
For the Reading part, you can highlight segments of text, you can also make text notes too, see image below.
In the online course we ask students to only send in computer typed essays.
Disadvantages:
More expensive (around 100$ usd more)
You can't write or draw on the question sheet, potentially bad for the listening and reading
Writing task 1 - might be harder because you can’t take notes on the question paper
Highlighting text takes much more effort and wastes time, following maps is more difficult, etc.
Advantages of paper based IELTS (traditional)
Cheaper (around $100 usd less)
Works better for slow typers
Possible to make notes on the question sheet, helpful for tasks including maps and highlighting key words
You may make mistakes, but you certainly won't make a typo
Disadvantages:
Most younger people, myself included, do type faster than they write, so the writing part will be slower for the majority
Students with poor handwriting could lose points (more info here).
Have to transfer answers to the answer sheet, increased chances of making mistakes
Fewer tests, longer wait for the results
Speaking could be arranged for another day
Dmitry, a student from Russia, told me that he was at a 6.5 previously. He took the computer-based test and managed to get 7. He was convinced it was because it was computer-based.
He said he suffered from writing slowly, and his handwriting was poor.
I think this is quite common among students nowadays, especially those who don’t use the Latin alphabet daily (Chinese / Russians etc).
Nowadays almost everyone is typing on computers, for work, school etc.
