I'm planning to teach online and after taking the TEFLPros course, I feel really prepared. There are some elements of the course that didn't exactly apply to me (like how to set up chairs) but I don't know how you could get properly certified without knowing this stuff, basically I'm saying the course is comprehensive. The thing I really liked was how they showed me how to adapt my plans to different situations. The course has a lot of video which was another thing I liked. I get bored if I just read stacks of text so it was nice to have mixed media. I also felt like by the end of the course I knew the trainers which I wasn't expecting so that was a nice touch. It was a great thing to undertake while in lock-down, gave me some structure on the tough days. Highly recommend.
