It's not a memory game. Even if you did remember everything long enough to repeat it, some of it will be gone from your head as soon as you've read it back to the controller!
As others have said, you write it down.
What they didn't say, is that once you have it written down, you should then read back not what is in your head, but what you have written down. This prevents difference between what's in your head and what you have written down.
Don't be in a rush to read it back to the controller before you've written it down. Write it down first, then talk.
