Review on TESOL 120-hours course

This certificate is undoubtedly important as a lot of employers require some kind of an approved license, and it can also be helpful for self-employed teachers to show their qualifications. There was hardly new information for me as I graduated from the university as a teacher, although it was a good way to revise my knowledge and it's a wonderful source for beginners to get to know the basics of ESL teaching. I haven't used a mentor's help, but based on my subjective opinion about the organization, I'm pretty sure it's working properly.
