Classes start any day of the week. On Sundays and official holidays, there are no classes. Missed classes (because of a holiday during the week or previously announced sick leave) can be made up at any time. Saturday classes are possible at the same price. We can form small groups before excursions or in exceptional cases.
The classes are one on one, that is one teacher works with one student; however, small groups can be formed circumstantially, with topics of common interest, such as grammar, literature, history, social concerns, economics, etc., for intensive discussion and practice of the language. Beginning students have a teacher who speaks their own language or another language common to both.
We must also mention that our practice of changing teachers every day has yielded very positive results. Each of our teachers brings his/her own experience into the classroom, and these vary according to the contexts in which each has lived and worked. Often the teacher-student interaction blossoms into friendship.
