I’ve been studying almost 2 and a half years and no I’m not fluent, I’m not certain but probably intermediate/conversational level. If you’re self-studying, like me, I think talking to people in Korean is the most important thing, especially for speaking and listening.
These are the things I did: learnt basic grammar and understanding of the language through TalktomeinKorean lessons, wrote on Lang-8 to practice and met language-exchange partners to talk to (text and voice) on Skype and Kakaotalk (also met people through Hellotalk and Sharedtalk), every time they used some grammar I didn’t understand I googled it and learnt through the sites talk to me in korean, how to study korean, clare you and eunso cho (berkley), korean grammar dictionary, korean wiki project, and more. practised reading and listening.
The best advice I can give you is try to learn a balance of everything, be careful of perverts, and don’t. be. afraid. of. speaking! Everyone you talk to will know how hard it is learning a language and it is absolutely okay to make mistakes, the important thing is that your meaning can be understood. Also, have fun with it!
