And yet, a.k. you'd doubtless concur with the rest of those here that Polish compared with English is much more phonetic and pronounced as written!! Poles "under 35" too have their language quirks, and perhaps you as well (though you's scarcely admit to them in open forum among virtual strangersLOL)
Where pronunciation may not be across the board as challenging as over 35, what charactarized 'Poglish' is frequent over use of vulgar slang, more than's called for very often. Subject-verb agreement also remains a challenge for many Polish native speakers using English.
you can try to watch videos in youtube.com search for things like dokumentalny (normally they have english and polish voice together, that can help for unknown vocabulary), that helped me a lot.
Also I recommend you to get some book (maybe you can order them online), search for Polish in 4 weeks (maybe you will not learn in 4 weeks but it is a good guide)
Also you can find some online teachers in: .e-korepetycje.net/ , gumtree or similar, if you are looking for free in difriends.com you may find people who are willing to teach you polish for free in exchange of english or other languages :) powodzenia
I also tend to agree that it is entirely possible to learn Polish, for that matter, any language, while not living in the country! This can be done through excellent, FREE sources such as bookbox.com and a number of other similar language-learning sites. These provide endless hours of enjoyable exposure to a foreign language with handouts, songs and other learning exercises:-)
Furthermore, long before I ever went to Poland, I watched Polish movies of varying sorts with Polish subtitles rather than English. With closed-caption, I could shut off the Polish subtitles and simply watch the film, absorbing the language uninterrupted while viewing.
Although there's no long-term substitute for being in the country itself, short of that, one certainly can acquire a foreign language from abroad. I can attest to that!
