It's a short but helpful lecture. If you don't have background knowledge about OPIc, it's worth listening to.

I started OPIc for the first time and got a good grasp of the overall framework I was having difficulties with OPIc, but after listening to this, I was able to start easily. Thank you

I was in despair because I urgently needed OPIc, but fortunately I found hope after taking this course. I'll do my best to prepare and bring good results. It was very helpful that you delivered only the essential points without unnecessary content. Thank you~!

While watching the instructor's lectures, I was able to recognize that the purpose of the exam is to achieve IH, not contextless English study. It was a very useful class as I could systematically establish strategies in a tight timeframe. Thank you!

The content was concise yet effectively conveyed the key points, which was very helpful. Thank you :)
