The Duolingo English Test consists of two parts – An Adaptive test and a Writing and Speaking test. The duration of the adaptive test is 45 minutes, whereas the writing and speaking test lasts 10 minutes. The former contains a series of different questions which will analyse your English language skills, whereas the latter has open-ended prompts which you can share with the institutions of your choice along with your DET score. In the adaptive test, the difficulty level of the questions will alter on the basis of how you perform. For the speaking sample, you will get 1-3 minutes to record your response and for the writing part, the response will have to be recorded in 3-5 minutes. The International English Language Testing System or IELTS exam contains four parts, namely – Listening, Reading, Writing, and Speaking, on which the test takers are evaluated. This exam has two formats – IELTS Academic and IELTS General Training Test. The former is used by higher education institutes across the world where you wish to apply for the purpose of UG or PG programmes. If you wish to migrate to a major English-speaking country or want to move to a different nation for employment-centric training you can give IELTS General Training.
