The "longest" Duolingo course can be interpreted in two primary ways: by the total number of levels or by the total number of lessons. Based on available data, the English to Spanish course has the most levels, while the French to English course contains the highest number of lessons.
Duolingo measures the length of its language courses through different metrics, reflecting the comprehensive nature of its learning paths. Learners might consider a course longer based on the sheer volume of content units, such as levels, or by the granular amount of individual practice segments, known as lessons.
Courses with the Most Levels
The course with the most levels offers the broadest progression path through the language. These courses typically cover a vast range of vocabulary, grammar, and thematic units, organized into numerous distinct stages of learning.
- The English to Spanish course is currently the longest in terms of levels, providing an extensive learning journey for English speakers aiming to learn Spanish.
- Following closely are the French to English and Chinese to English courses, also offering significant content depth.
Courses with the Most Lessons
For learners who define "longest" by the sheer amount of practice sessions, the number of lessons is the key metric. A higher lesson count indicates a more detailed breakdown of topics, potentially offering more opportunities for repetitive practice and skill reinforcement.
- The French to English course stands out with the highest number of lessons, making it a very detailed and intensive learning experience for French speakers studying English.
- The German to English and Japanese to English courses also feature a substantial number of lessons, indicating a rich and thorough curriculum.
