Do you know where I can get the best course in order for me to get a TESOL Certification? And if someday I want to teach English, what kind of Certification would be the best I should get and where I can learn the course?
The main thing is to check on how useful the course is- there are many courses being offered that are basically bits of paper. Check that it is genuinely internationally recognised. The CELTA course is one of these- you can use it anywhere. If you're thinking of a particular course, let me know and I'll have a look into it. I did ESL courses with people like International House and the British Council, who are universally known and respected.
