what do you think of the English training center is useful for you?

Every coin has two sides.It depends on you.
If you want to improve your text-English such as grammer and vocabulary it is usful.But,make sure you need it,don`t waste time on doing something witch can not help you.
However,if you only want to practice your speaking skills,in my opinion,you don`t have to go to there.You can listen to English songs watch English moves and other ways like that.
