Question

How should I study Korean, and how many hours should I study it?

Answer 1

I recommend you to make Korean friends. By the way I’m Korean :)

Answer 2

Well for me, I'm learning Japanese right now. The first thing is to learn how to pronounce their vowels. That's really important and makes it easier to pronounce the word. Also learn how their other letters sound.

Another thing you can do is to watch movies in Korean with English subtitles or movies in English with Korean subtitles.

P.s. I'm learning Romaji so the first tip applies more to Korean in English writing. Example: Annyeonghaseyo

천만에요 :)
