Excuse me, cause you mentioned that “In the real test, if you try to correct your mistakes, this will make your talk like learning by heart rather than speaking” . So you meant that: I should not correct my mistakes to make it more natural. Am I right?
I mean in the real test that you try to correct your mistakes will make your talk sound like learning by heart rather than speaking. It is just an advice for you that you should not correct all the mistakes you made and continue to speak.
