Today, without being told, we took a pop quiz, which is very surprised that I didn't study for it at all. The quiz included the facts which are what classmates shared in class few days ago. Because of my terrible listening, I didn't understood too much about what they were talking about. As a result, I just got 20 of 30. It's not a good news for me. If I can understand what they are talking about, my grades would be higher. I think this class is so hard for international students whose English are not so good.
