Hi!
I've already done all the Pimsleur lessons, and I'm using Duolingo for learning Romanian too, as well as obviously conversing with native speakers, but there are times like when I'm at work that I am obliged to just sit around and am not able to talk, and not able to use computers, but it's permissible to have a book.
So, I'm asking for recommendations of exercise books/workbooks, for learning Romanian...
??
