Certificate in a short time

I have been teaching English for 1,5 years and finally did my TEFL. I finished the course in one week, studying for one hour per night. I liked the theory and practical tips that the material had. After studying I tried couple of the activities in my lessons and children love them. It's great to finally have a proper knowledge about English as a Second Language teaching - it makes me more confident as a teacher! And of course, I'm happy to receive my certificate in the end. And it wasn't expensive!
