If you’re planning to study in the United States in 2025 or later, the Duolingo English Test (DET) has become one of the most efficient, affordable, and fastest ways to fulfill English proficiency requirements. Unlike IELTS and TOEFL, which require test centers, strict appointment schedules, and higher fees, Duolingo is completely online, costs only $65, and provides results in 48 hours.

However, achieving a high score (120–140+), which top US universities prefer, is not as easy as it sounds. The test is short, adaptive, and highly skill-based. If you don’t prepare with the right strategy, your score may fluctuate.
