Excuse the double post, but I found another
really great resource for learning Korean ! It's by an accredited University in Korea and has video classes in English and Mandarin that not only teach the Korean language pretty quickly and effectively but also explore Korean culture a bit. I highly recommend this maybe after you've gotten solid in the basics / the Hangul writing system with the last link I shared
EDIT: I should specify for that link because the site might be a bit confusing that the specific resource I'm talking about is
this playlist (although if you go through that channel's playlist they also have introductory videos in Mandarin, and I believe I saw some in Spanish somewhere around there but don't quote me on that)
