You may plan your own programme aswell as your schedule if you so wish.Each lesson is one-to-one (1 teacher + 1 student):
you advance at your own pace and level;
you save a considerable amount of time learning only the vocabulary suited to your needs;
if you wish, you can bring along your own materials;
these materials can be worked into your lessons.
From every point of view you progress faster than in a group.
You decide for yourself:
the day your programme begins ;
the number of lessons each day ;
the number of days or weeks ;
the objectives you want to accomplish ;
the materials and teaching aids relevant to your particular needs which you want included in your lessons. (You should bring all such materials with you).
