The 140 hour course was informative and helpful. I took it as a requirement to teach English online to Chinese children- a requirement of one of the companies that interested me. I have a teaching background so it was not difficult but I did learn some new information about the differences and challenges of teaching English as a foreign language. The modules on grammar and teaching vocabulary not non English speakers was particularly interesting. The final essays were QUITE challenging. I needed the full time to complete them and the final test was also thorough. a very good experience.
