I would give zero stars, if this were an option. Began my third year of it a few months ago, but am ready to ditch it. The quality of their course and the customer service (which is really non-existent) have gone downhill rapidly. For several months now I have emailed (you can't speak to anyone) with the (1) issue of words I haven't even learned yet appearing in practice sessions and (2) words I have recently learned and want to practice almost never appearing. I have emailed three times, but no fix or solutions by Duolingo. So now, not only has their quality deteriorated, but my learning experience has gone downhill because of them. Time to move on. VERY poor management.
