I'm still struggling with reading. It's not necessarily 'easy' for everyone to learn. I just can't get my head around the letters for some reason, but I'm signing up for Korean lessons, my coteacher is also trained to teach Korean to foreigners (she's brought in some letters to help me practice) & I do pretty well at remembering phrases to get by in, which is what I need more than anything - to be able to communicate with people!
Don't feel bad....it is definitely not something you'll learn in a day, despite the claims. I used to ALWAYS forget stuff like 워, 와, 왜, 왜, 웨, etc.... Even ㅕ,ㅓ,오,요,우,유,야,아 are hard at first.
People who say they "learned it in an afternoon" usually mean they "learned the basic consonants in an afternoon." Quiz them on the vowels and I think you'll see the limits of what they know.
Here's a trick, though: start remembering words where troublesome letters appear. For example, once I noticed the 워 in 원 ("won", which is written everywhere), I always remembered the ㅝ sound.
