Yes, I have. When I was 1st year and started to study with foriegn teacher first time.
I felt fear and woried very much. At the began, I can't understand what was teacher said.
When he ordered homework I still don't understnd him. That make me practice a lot.
I tried to study hard and listening everything about English; listen international music, chat with. foriegn friends and watching cartoon in version English. Now, my skill isn't perfect.
But I think, it's changing from when I was 1st year very much. I can say with forieng teachar without shyness. Although I think it's improve a lot I still know by myself it isn't good enough.
I need to practice more and more. Hope someday, my language will exellent.
