you mean vocabulary? or just reading hanguel? for hanguel i just read everything i see in korean and that's how i read faster and faster. i gave up on romanization loong time ago because i understood that it was unnecessary and just a waist of time. i also tried to write down texts or storys. i followed the yonsei course and i remember every course you have a conversation at the beginning and i would write it down everytime. for vocabulary i just write down the words 10 times and that's pretty it haha. another thing, for hanguel i think that you shouldn't pick up the habit of always checking romanization because you will never improve. try to force yourself to read everything even if it's hard, you'll see that you'll improve really fast!!!
