  1. CA,

    In Lesson 4 Honorifics, I appreciated the nuance of when to use 세요. I only intuitively picked up that it is used when asking someone to do something but not the greater sense that it is used when speaking about others to show them honor. Which is why its not used on sentences about oneself.

    • Talk To Me In Korean,

      We really appreciate your detailed and positive feedback!🙂

  2. DebiT,

    This course has so much useful and helpful information. Thank you Billy and TTMIK!

    • Talk To Me In Korean,

      Thank you for taking this course and leaving the comment! 🙂

  3. Carlos Sito,

    In lesson 17 you say we can’t use 때 to mean “when I see you it will be fun” since it refer only to the moment and that we should use “If/면”no instead, but what if we want to say literally “When I meet you it will be fun”? Like the whole time we are together because you know that you will meet for sure and it will be fun. Thanks

  4. Gerone Mercado,

    I’m in the intermediate level and this is like a quick refresher from the previous lessons! Lessons are short but very well explained! I especially appreciate the pronunciation lessons. Good job, Billy! I wonder how many years it took you to master the Korean language. I aspire to be as fluent as you are! 🙂

    • Talk To Me In Korean,

      Thank you for your feedback! 😉

  5. Ian Paul B. Saligumba,

    Thanks Billy! I learned a lot from this course. To more awesome video collaborations like this please

    • Talk To Me In Korean,

      Thank you!

  6. Leeya Davis,

    I think this course is a must-have for Korean learners. I’m low/mid intermediate and found a lot of the mistakes have to do with nuance or how you’ll be perceived. Like Billy says “technically there’s nothing wrong with this sentence grammatically but….” [insert Billy teaching you how to really get across what you want to say and/or how to sound more natural]. I love this course, money very spent!

    • Talk To Me In Korean,

      Glad you enjoyed the course!

  7. Heather Schnau,

    이 수업은 정말 도움이 돼요! 저는 이미 제 실수를 일부 고쳤어요. 정말 감사합니다! ♡

    • Talk To Me In Korean,

      도움이 되었다니 기뻐요! ❤️

  8. Andrea JF,

    I recognise that I used to make many of these mistakes at first and watching these videos at the time would have been so helpful! Even if I don’t make these particular mistakes anymore, I’m quite happy to have seen all these. Some were very helpful in understanding the reason behind it all . 🙂
    선생님들이 가끔 빠르게 말하는데 다 이해할 수 있어요. 비빔챗을 들을 때 빠르게 말하는 사람들을 이해하는 데 천천히 익숙해 줘요.

    • Talk To Me In Korean,

      정말 대단해요. 한국어 공부 화이팅!! 🙂

  9. Lydia Godwin,

    Billy this is an incredible course. I have always said it is just as important to know what not to do and say as it is to know what to do and say. The additional examples spoken by native Koreans at the end of each lesson to round out each lesson was well thought out. My only disappointment was with some of the longer sentences, it felt like the speaker was going to fast, as if the speaker wanted to complete the sentence before taking another breath. The male Korean speaker was very good in that he spoke at a good pace and stopped for a split second before completing the sentence. He is very animated and comes across as very caring in his teachings. Billy thanks for explaining the cultural part of what not to do. I definitely want to say it correctly, As we all do who endeavor to learn the Korean language. I had seen your youtube lessons but to see it here on this web site is even better! Just awesome!!! I will review many of these lessons again.

    • Talk To Me In Korean,

      Thank you so much for your detailed feedback. 🙂 The speed of women’s speaking seems to be normal or a little bit slower, but we will make future videos, referring to your feedback. Thanks for your valued time and learning Korean with us. 💖
