Coming to Vietnam and obtaining my TESOL was simple and smooth process. Being able to have hands on experience was great as this is my first time teaching. There's quite a lot to do in the 4 weeks (observations, lectures, essays, lesson planning, practice classes, eating and drinking!), but once everything is done - you'll feel ready to take on any class.
One of the things I liked about the course is that it gives everyone a chance to network with other new teachers - this makes the whole process of moving to another country slightly less lonely.
I was also given help to find a job and everyone on my course was successful in finding a job.
All in all, I am very happy with the course.
