The Duolingo English Test (DET) is generally considered easier than the IELTS for a variety of reasons, including the exam style and focus. The DET is computer-based and takes only 45 minutes, whereas the IELTS will take up to 2 hours and 45 minutes for a paper-based version. The Duolingo English Test focuses on fundamental language skills like grammar and vocabulary, but the IELTS evaluates a broader variety of abilities, such as speaking fluency and advanced writing.
