study groups

I am in 2 study groups to practice English.

But, I have to choose 1 of them to be changed due to time schedule. The one I am in is good to hear other's speaking because there are many English teachers. And where I like to move is that I need to study more than any other groups. They use Ted scripts and topics to talk with, debates.

Why i am hesitating to go to my group is there are too many people coming. I had conversation with around 10 people. It means I can have less opportunity to speak out. And I meet 1 American, 1 Gyopo.

I guess I need to study English more, not to have more opportunity to speak. But I still don't know which is better for me.

Okay! I decided.
