Are the Official Cambridge Tests as hard as the real tests?
About week ago I got 6.5 in reading and 7.5 in listening from Official IELTS practice test.
But today I got 7.5 and 8 in reading and 8.5 in listening from Cambridge IELTS 8's two tests.
Such significant change brings mistrust to me.
Are Cambridge's tests easier than real one?
If so Where can I find harder materials, since I don't want to be misinformed.
