Isnt that a school site singing the song of praise for that "company"? If so, it is quite unlikely that real authentic and truthful information is given there. So, to me looking at this site and reading the info given there is a waste of time to me!
Perhaps more importantly, foreigners seeking teaching jobs can get a fair idea of the English levels of those four practising teachers by reading their submissions. After having done so, many a non-native speaker having poor English can probably apply with confidence for a teaching position there.
Why are you posting it here anyway?
Did the bosses of IELTS Yuncheng outfit "compel" you to post that stuff here in order to toot their horn?
Or did they pay you?
Whatever may apply, I do not trust your words at all.
Obviously,you do not wish to debate my reply to your post, because you haven't even attempted to discuss the points I have made in my post. So I needn't and won't treat your post as it should be treated!
