일기 칠 - 한국어 교과서 I decided to remember 1,000 vocabularies because people told me that these vocabularies will cover 90% of daily conversation. The textbook I am studying is called Integrated Korean, published by University of Hawai'i Press. It contains many Korean vocabularies and phrases. Each day, I will learn ten new words, so it may takes three and half months to do so. 화이팅!
