I love learning and helping other people learn, whether it is with a language or something different. I also love doing handstands and flips!

    Dear TTMIK Staff,
    I think the work you do is awesome!!! I really liked the videos, ” How to Read and Write in Hangeul”.
    In the 1st video you stated that is a 5 video series, however I can only find part 1&2 on You tube, could you please help me or tell me where I can find parts 3-5?
    Please and thank you,
    Kelly Gothra

    Hello, i really enjoy listening to your pod casts. They have helped me tremendously. I got through level 1 and noticed that you also have textbooks for level 1. I really wanted to purchase a copy but there is apparently none in stock. Do you mind letting me know when you will be expecting another stock of them? it would be highly appreciated.
    Thank You:)

    i have been to one of the meet ups 2 years ago when i travel through seoul.
    i was wondering if i can make an appointment to visit the office?

    hello dear Mr. hyunwoo sun
    I was so curious that what is this “han” part in hangul,hanguk,hanja and 汉字hanzi (Chinese characters) means?
    and teacher is there any personal tips from you on memorizing Chinese characters for me??…I’m actually learning traditional Chinese beside Korean but it is so hard to memorize the characters, as you said that you know Chinese too I was wondering if you help me too…and by the way thanks a lot for all your kindnesses at ttmik I really enjoy the lessons and I’d really liked that you had another web site that was talk to me in Chinese!!!therefore I could improve my Chinese beside Korean…
    thank you again

    I would like to start learning Korean soon, using this website and starting from Level 1 and I am considering buying the TTMIK Level 1 Workbook – does the workbook come with answers?


  • mila

    hello Mr. hyunwoo sun
    you’re my favourite teacher in TTMIK…and of course ms. kyeong-eun choi is my favourite too…i really enjoy the way you teach korean.
    i want to ask you something…why people in korea always call name and add ssi at the end of the name. it does meaning something?.
    thank you very much for the answer…

  • Sonia

    Few months ago you had books like secret garden in the store but now i cant find them
    Any chance you would be selling those again?
    Thank you

  • Liesl

    Hi Hyun Woo!
    I’m chilean and fan of this incredible website, which I recommend to almost every friend that loves Korea. Unfortunately, this year I couldn’t improve much in my studies of korean because was taking the national test to enter to university.
    In a near future I’d like to go to Korea as a exchange student and I have question to ask you. In some universities in Korea they require me to have approved TOPIK LEVEL 3… Which level do you recommend me to have studied at this website as minimum to prepare myself for the exam?

    Thank you very much,

  • Dana Batyrgaliyeva

    Hello, Hyunwoo
    My name is Dana and I am from Kazakhstan
    Recently I have started learning Korean language. Because Korean language is not popular in our country I thought that self-study is the only way I can choose. I had come across several different youtube channels that do the same job as you do before I found out your website. Now I am in the middle of the level 2 of your podcast lessons and I find them very useful and informative. I can speak 3 languages (Kazakh-my native, Russian and English – as additonal) and it is really interesting to learn completely different language from perspective of languages that I already know. More I study Korean language more I find similarities in sentence structures and word meanings with my native Kazakh language.
    I am getting used to your teaching style and methods you use. And it is so cool that you have so many different directions in your work, not only teaching but publishing books, airing on the radio (which I find out just yesterday) and many other things to really get into the Korean language and culture. Thank you very much and I wish you and your team really great success on the project that you run with passion
