Starting with the basics
You want to understand your favorite K-Pop songs and want to understand K-Dramas without the subtitles? No more procrastination.
Here are things I did or used to get better at Korean:
Learn Hangul
It´s so easy and you can learn it very quickly in a few days.
2. Do not use Duolingo
This was my mistake for a long time. Duolingo wont make you proficient in Korean. They also dont explain it very well. Just dont waste your time with it and ditch Duo.
3. Use the correct textbooks and websites
Talk To Me In Korean is a goldmine. Seriously. Use them. There are also PDF version if you dont want to learn with a physical book. They go through all the basics with you in a very nicely explained way. You can also use their website for further grammar lessons or listening practices. Can recommend! Also, if you´re stuck with a specific grammar, just google "xyz grammar in Korean+ meaning/grammar". E.g.: -는 거야 grammar. There are many websites explaining it simply and quickly.
Plus: Watch YouTube Videos of real life conversations. Often these are also shorts, so you do not have to watch a 10 minute video. Replay those shorts a lot until you understand what the Korean speaking person is saying.
