I thougt it was a great idea to learn with ef and to start a 1-year-subscription. But for me it is a waste of money. I don't learn within the app and the privat lessons are not very useful as well. I have rarely lessons with the same tutor twice. And so I have to learn very often with a tutor which I don't like. I am sorry, that is a waste of time and money in my opinion and for me personally.
