I don't mind, as long I can translate it. I'd like to get more sentences to translate into Portuguese. But I really like Duolingo and I've learned a lot, very fast. Too bad it's still in beta, but I try to help all I can by making reports.
I think it would be a good idea to buy a book. That may help you a lot as well as listening to songs. I dont do portuguese lessons anymore, but reporting is a great tool to make the site better
