I am currently doing the 180 hour TEFL course and although I mostly enjoy it, I do have a few points to make: 1) there is no option to listen to the course via audio file which is not great for people with hearing impairment or those who are just better at perceiving information that way, and punctuation is awful on the site so using text-to-speech app just won't work as well; 2) each section definitely takes more than 1 hour which makes it hard to split your lessons into equal parts (I prefer to only spend 1 hour every other day on the course, and it's impossible for adults who's memory isn't as great as it used to be). Some examples are very outdated and can be perceived as insensitive in our day and age (e.g. as an example of comparison in vocabulary you chose "girls vs boys", well, what if your client is non-binary or trans?).
