Find out what your interested in Korean. I do like. Korean dramas and I don't. Really like korean music. But I lovw korean food and the language and hoatory. So fo me, I try to read things or watch things about my likea. I also work solely on improving my conversational skills, as that's what I want to improve. You can watch dramas etc. But unless you have a wide enough vocabulary and understand how koreans speak colloquially with the relevant grammar, I think its pretty hard. Not to say you can't do it. My experience, I have been learning almost for one year extensively, amd the best learning tool at your feet is just speaking to koreans. My korean has improved a lot. This is also because Korean people will see you trying to speak korean and usually slow their speech down for us to understand. Good luck with your studies.

In my case, watching same movies many times, talking to friends, and of course having interest in culture help me a lot when I am learning English :) Good luck!

I think you mean to say "to IMPROVE" your Korean.I can't help you with that, I am an English teacher ;-)
