Time flies, isn't it? (Time flies doesn't it?)

My English conversation class has(began with) 8 members. As time has gone, members are decreasing.(As time has gone by the members have decreased.) Last class made it with 3 members. (The last class there were three members.)  A Chinese, Indonesia guy, the USA teacher and me played a game. (There is a Chinese, Indonesian guy, a teacher from the USA, and me played a game.)  When they are it was their turn, they talked about topics that they have already chosen. While I joined the group, I had a chance to know(learn) about different cultures. Actually, I had hard time listening when the Chinese, and Indonesian guy said(spoke) because I am not accustomed to listening to another accent and pronunciation. SomedayOne day, I asked my English teacher about that.
Which accent is hard to understand? She said to me, "It's same for me."
Except for my English teacher's accent, it is easier for me to listen toKorean accent.
Maybe, I get got used to the Korean accent. Every week, I joined the class for 50 minutes. That time is very short. When every students, 8 members, join the class, we made 4 teams. Each team members talks each other. It is very important to sit because of that.

I am not good at speaking English. But I try to practice English if I have a chance to speak. Because I am not fluent in English, sometimes I stopped talking . Time passed. I finally said "That's it" or "Pass". I regret not telling well. (I regret not talking more.)
50 minutes are is very short. It takes 40 minutes to get to the academy.
So Every time I try to study English hard.

Good job, your writing is very good, and keep practicing!
