Korean first steep - Coursera free course
If you are a total beginner like me: https://www.coursera.org/learn/learn-korean
If you want to catch up withyour friend ( and maybe even do some teaching,) try this Korean fellow's posts https://www.youtube.com/watch?v=zO5vfF8ZrOAt=52s
I'll give this a go. I signed up for Coursera a year or so ago, but never used it. I also found a Mandarin course starting tomorrow. Hopefully these will motivate me, as it's more like a class so assignments are due!
