Do it

If you think this going to be easy forget it. This is an intense but very rewarding course and worth the $$ & the effort you will have to put in.
Kathryn is a great teacher. She's firm but fair and extremely knowledgeable about teaching and what you will need to know in order to teach English as a foreign language. Just wait till you get to the grammar lesson!!
Seriously if you are considering a TEFL course give this serious consideration. Not only are you in a beautiful part of the world for a month but you are also getting QUALITY teaching and support...1/2 the class I was in had jobs before the course was finished. Why/how? Because this course is recognized as one of the best. As that athletic company says 'just do it'...you will be exhausted at the end but you won't be disappointed.
