Review on the 60-hour course Dux Tefl/Tesol

I am a freelance teacher of English and German language located in Greece.
As I consider myself a life-long learner ,I keep trying to upgrade my skills/methods through various educational tools in order to equip my students.One of these ,is attending the 60-hour online course in Dux Tefl/Tesol;I have to admit that it has been an informative up-to-the point online course.A great number of querries have been answered.
Thank you for this trip of knowledge!
I am really looking forward to another course!
