I can suggest to use http://hanmun.vdegenne.com/ this website. This is a website I developed when I was active in learning Korean. I am a self-taught and engineer, passionate about languages (specially Korean) and new ways of learning. I still operate and add new words in the website every week. Maybe it will be a bit disconcerting at first sight but if you learn how to use the website you will quickly learn new words. I am sure about that because it helped myself A LOT. Don't hesitate to ask me questions if you don't understand how to use the website. Good luck :)

Tried checking the site but this cannot be found

memrise.com is amazing!
