I will study hard using the content you lectured on. Thank you!

Thank you for your words that really hit the nail on the head. I feel confident now. I think I can prepare well for the exam even in a short time. I'll do my best on the exam.

Lecture based on high school graduation I like that you taught me the key to getting a good score, rather than just memorizing filler words and studying like I did in Gangnam

To be honest, I feel like the person explaining it is really good at explaining it. I will try my best like the instructor!

This is not a lecture on OPIC English sentences, but I think it is the most helpful lecture for the OPIC test. Among the OPIC lectures I have taken so far, it seems to have delivered the tips and know-how most concisely. I feel like I can do better this time. Thank you.
