The sequence of the paper-based test is writing, reading, and listening. The speaking test is a face-to-face interview with an IELTS examiner, and you can sometimes select the speaking time slot, which is usually scheduled one or two days before or after the writing test. Your IELTS test results will be published in 13–14 days.
IELTS on computer and IELTS on paper have the same structure, question types, time allotted to each section, and material. The only difference is your experience on exam day.
