Can I start group lessons any day of the week?

In the Pal and Arinsal sectors, the three-day, four-day and five-day courses start on Monday, while the two-day courses start on Saturday. It is not possible to start on another day of the week, except for special departures on 27 December (for 3, 4 or 5 day) and 2 January (for 3 or 4  day).
