I took the class because it had the content I needed. The content was okay. However, the inaccurate pronunciation of English terms was a bit annoying..(For example, FOREIGN is not 포리존 but 포린키 because the G is silent.) Secondly, I didn't like the fact that the same words were said two or three times. If you remove the duplicate words, you can finish it in a shorter time, or you can convey more knowledge in that time. I know because I've done it myself, but it's really not easy. Nevertheless, you made the materials and even gave the lecture at dawn... thank you for your hard work. ^^
