Due to the nature of my job as an educator, I often create lecture materials. And I am a MacBook user who uses PowerPoint more than Keynote. Whenever I prepare a new training course, I often get stressed out because of my poor skills, despite my desire to do well. That is why I applied for this course without hesitation when an acquaintance recommended it to me. Usually, it is not easy to complete this online training course, but as the work-from-home period began due to COVID-19 and the period became longer, I was able to take the course consistently and enjoyably. Clean training materials, Clear content delivery, And great tips generously shared. This is often called 'cost-effective' right?^^ I was able to learn a lot at a low cost. One thing that was disappointing was, (I will probably improve this in the next course) The soft voice was transmitted through a good microphone, so when I focused, there were times when the flow was broken when a dry cough was transmitted as it was. Maybe it's because I'm too sensitive.^^; Anyway, I really enjoyed the lecture! You said there are 4 months left. I can't help but pay attention to the technical things you mentioned in the latter part, but I'll try to look at the things you emphasized in the beginning again. I regret not being able to attend the lecture you gave to physical therapists in Gwangju two years ago. I hope we can meet offline someday. Thank you!
