"Do you think you can learn a language well on this website?" It would be more difficult to completely learn a language from beginning to end on this website, from what I have seen. However, from my experience, this site can be a valuable addition to a separate, central course of study, if you use it correctly. You would use it in the same way that you use a tutor - as an additional source. It is worth the time spent on it. I obviously feel that way, or else I wouldn't be here.
