Following are the differences between IELTS and TOEFL:While TOEFL is ONLY computer-based, IELTS is both paper and computer-based. So if you’re more comfortable taking an exam on paper, you can choose IELTS. The speaking section for these two exams is so different. In IELTS, you have to appear for a personal interview. This isn’t the case in TOEFL, where you can speak to the computer during your online test itself. They take TOEFL in standard American English. So if you’ve grown up watching English movies and binge-watch sitcoms even today, TOEFL might be for you. The essay they expect you to write in the TOEFL writing section is lengthier. It also demands a fast typing speed. On the other hand, if you type slow but have legible handwriting, you can go for TOEFL.
In IELTS, you have to give short answers, which is not the case in TOEFL. TOEFL requires you to attempt MCQ-type questions. The reading passages in TOEFL are also used to inform rather than entertain. This means that if you like reading non-fiction, news, etc., you will find this exam easier to attempt.
