Oh and go to www.japanesefromzero.com they have a free sign up and you can take free classes online. I use their workbooks I buy off amazon along with it but I assume you could take your own notes. They do Korean from zero too.
Yea. There are extra things you can buy but I haven't paid for anything. If you did want complete access, there are classes with teachers and things like that it's 14.99 this month. I just use the free stuff.
Download mondly. You can learn as many and any language you want. I am using it for Japanese and Korean. You can choose to study in romaji or kana or romaji or Hangul. It's the greatest app ever! Seriously.... Love it!
