My in person 3-day training in Edinburgh was excellent - top quality and I have absolutely no complaints about it! The online classes however I have been pretty disappointed in. The content is fine but the videos take a really long time to load, are hard to navigate, and don't have options for changing the speed of listening which makes reviewing videos or going through topics you already know tedious. Given how much you pay for the online classes I strongly feel that the platform needs updating and made mobile app friendly. I have bought an online Chinese course (HSK Zero to Hero) that is run on Teachable that is very simple to use and would be ideal. The lack of ease of use and ease of access to the Tefl.org videos has resulted in me failing to finish the course by the expiry date and by the expiry date of the extension that I bought. The interface could, I think, be made enjoyable rather than tedious to use.
