French, Japanese & Romanian Resources
I made a list for Intermediate to Advanced French learners because that's where I am and I don't really have any resources for lower levels so if you have any please feel free to share for the beginners! Also make sure to check out the comments section because people have made some great additions to all these posts: https://www.duolingo.com/comment/25416107 Here I suggested some movies you can watch in French that I am fond of: https://www.duolingo.com/comment/25464798
I made a giant list for Japanese learners of all levels here and again, check out the comments as they make some great suggestions as well: https://www.duolingo.com/comment/25476550
This is a post that I found useful for Romanian: https://www.duolingo.com/comment/19075872 However, I have seen many people say that it is much harder to find resources for this language and I agree, here are some of my suggestions:
1) If you have a friend in a foreign country (specifically Europe) where you are more advanced in that language, ask them to look for books and maybe you could work out a way to pay for it. This isn't exactly cheap but I have a friend in France who helped me find some books for Romanian. This will help me not only with my Romanian but also with my French! If you are also more advanced in French and looking for a Romanian textbook look for Assimil for Romanian, you can get it on amazon I think but it isn't exactly cheap.
2) If you are not as crazy as I am and have 95% of your friends living in foreign countries (heh) there is this book: https://www.barnesandnoble.com/w/complete-romanian-beginner-to-intermediate-course-dennis-deletant/1122054212?ean=9781444105599 However, I cannot give you an idea of how good/bad it is.
ALL 3 LANGUAGES:
1) This site is fun, you can put the main language of the site as the language you are most advanced at and then say you are learning any language you want: https://www.internetpolyglot.com/
2) I have mentioned this resource in almost every list but here it is again because many people keep asking for others to talk to, find the app called HelloTalk, you can get away without buying anything and there you can talk to native speakers. If you wish you can pay to add that you are learning more than one language, get unlimited translations, etc.
3) There is also Mondly, there are ups and downs to Mondly that I think many people have pointed out before me. I got the lifetime access when they were just starting off and it was only 20$. So now I have no idea how much it costs to have full access to everything. However, what I like about Mondly is there is a conversation within every module where you can compare your voice and pronunciation to a native speaker. This would be very difficult for complete beginners as you cannot slow their voices down. While sometimes their conversations can be a little awkward I haven't run into any problems with pronunciation. I've even asked my native friends to check them. On the app they are also starting to do timed repetition like Duolingo but it isn't implemented on the site yet.
