TEFL program is really useful and very interesting. Rio is fantastically active city, full of life, music, sun and pleasure. It can be difficult to teach in Brazil because of cultural distinctions, but it does the work even more interesting.
What would you improve about this program?
It is necessary to know that teachers of a course are Brazilians. With their features, as personal so professional. Teaching Americans gives them more pleasure than teaching others who wish to teach English abroad.
