The Duolingo English Test is an exam designed to evaluate someone’s English language skills. It’s different from traditional exams because you take it online, and it’s adaptive, meaning the difficulty adjusts based on how well you’re doing as you go along. The test covers reading, writing, speaking, and listening skills, and it’s used by many universities and colleges for admissions purposes. It’s a convenient option for students because they can take it from home without needing to schedule a specific testing time at a center.
