What do I need to acquire a "High Intermediate" level in Korean?
I am an intermediate learner of Korean and I will go to live forever in Korea within 2/3 years.
To do so, I would like to get a high intermediate level in Korean, (for being able to communicate with other people with a certain degree of fluency), because I am currently at a low intermediate level. There is no website where I can found out the contents or an explanations about the knowledge I need to know to acquire the High Intermediate level of Korean. Therefore, in this occasion I am here to ask (specailly to Korean native Speakers or advanced learners of korean) what I need to know to reach the level.
Could anyone help me, please?
Beforehand, thank you so much for your time and for your replies : )
여러분 감사함니다! ^_^
