Writing: handwriting vs typing
The task is the same in every mode: five minutes of reading time, then 40 minutes to write a letter of about 180 to 200 words, with the case notes available throughout. On paper, legibility and neat corrections matter, and OET allows all capitals as long as you are consistent. On screen, typing speed and accurate keyboard work matter. Spelling is assessed under Language in either mode, so a typing slip counts just as a handwriting slip does.
Reading and Listening on screen
Reading has 60 minutes: 15 for Part A and 45 for Parts B and C. On computer, OET explains that Listening Parts B and C show one question per page and you click to move on; in Part C you navigate with tabs on the left. OET's tips say that on computer you can cross off answer options by right-clicking and select answers with a left click, while on paper Parts B and C are answered by shading.
Speaking: room vs screen
Both formats have two role-plays, and before each one you get three minutes to read the card and make notes. On paper, you are face to face and can write on the role-play card. Online, the interlocutor shares the card on screen, does an ID and 360-degree room check, and headphones may not be worn. At a computer venue, OET mentions a noteboard for notes.
Booking and results
OET states that computer results arrive in as little as 48 hours after all four sub-tests are completed, with 95% released within six calendar days. Paper results are released from 13 days after the test date, or from five days in India and the Philippines. OET calls all of these timeframes indicative. Computer and OET@Home bookings stay open until seven days before test day.
