Any Tips for Greek?
If you're a native speaker or just know a lot, there anything I should learn first or anything to help me along the way? It could be with the language or culture (because I'm very interested in new cultures).
There is a whole team of native Greek speakers ready and willing to help in any way we can. Just to start you off here is a list of resources and how to get the Greek keyboard etc.
These links will not only show you how to get the Greek keyboard but also how to find the Greek letters on it, how to add accents etc. https://www.duolingo.com/comment/22040507

As for culture, it's hard to know where to start as with any culture; it's rich and complex. I suggest you go to youtube and type: "life in Greece today" here's one to get you started:
