2025–2026: During the year it is possible to join courses that have already started, after completing a free placement test available here. New online and in-person group courses will start in January 2026, with registrations open from december 2025 (with promotional, lower prices for early enrollment) and open until the end of the month (unless places run out). From that date, the schedules, prices, and course details for each level will be available.

For the 2025–26 school year, on this page you will find the schedules (fixed day and time) for our in-person group courses with their respective locations, as well as the schedules for our online courses in French, Spanish, Russian, Chinese, Japanese, Arabic, German, Italian, Portuguese, and English. After the start of the courses at the end of January 2026 (the exact start date will be communicated by the end of January), you can check the calendars, course features, and available group packages here:
