You can use your browser for both, there are extensions(FireFox - PDF & EPUB/Chrome - PDF& EPUB) for that. In case, you want you use a separate software for them, I suggest SumatraPDF--it handles both PDFs and .EPUB files. Source: over 1 year ago
Give https://busuu.com/ a go, I think it does a much better way of explaining words and grammar than Duolingo. Good luck! Source: over 1 year ago
When I was starting out I used a subscription to Busuu and thought it was pretty good. They had listening exercises, vocab exercises, grammar/conjugation, and test exams. There's also a community feature where native speakers can correct some of the exercises you do (and vice versa). Source: over 1 year ago
I have been studying French for a few years (I still don't feel I would be very beneficial to you unfortunately, however) and a good place to look for language partners that I have found is busuu.com . A big section of it is connection to others learning your native language that speak your learning language. Just fyi if you want that info. (: Good luck!! Source: almost 2 years ago
Then I've tried Busuu premium, which is considerably better than Duolingo - at the very least tries to teach you grammar, and the video contents are really well produced. For an absolute beginner it is great! Source: almost 2 years ago
I learn english at busuu.com. One of my lessons contain phrase "i had dinner" and also "i had pizza". I am confused. Dinner and pizza it is countable nouns. Should I use "a" article? Source: about 2 years ago
