In view of Coronavirus I inadvertently changed my profile with TH to include online teaching in the vain hope of getting any clients and, as this goes to their Admin to approve, I am now, in the light of this thread, waiting to hear from them that I have to register to offer online. In this case I will have to leave them as I am not getting any clients anyway and when I was this was for £20 an hour, with all the marking and preparation this involved. Free lessons and 25% commission, this is simply and completely unrealistic when you are up against such enormous competition online. They won't get anyone staying with them. Tutors are the ones doing all the work, the preparation, the marking, and the buying of textbooks for specific courses out of any "profit".
