I made Korean-English flashcard sets you can study http://www.flashcardmachine.com/p/koreancards These were made for myself to study. It is not everything, and it is not well organized, but if you are looking for some flashcards, try these. (You do not need an account or log in! But it's a free website!) Various topics I have are: Family On the phone Colors Weather At the Airport Clothing & Fashion Travel Dormitory Boarding school Public Transportation At the Post office Advertising At the Professor's office Grammar Hanja (Chinese characters) There are 21 card sets! Hundreds of words!
