learn (something) down pat
To learn, master, or understand something perfectly, to the point of requiring little or no focus to do, recall, or accomplish it. I made sure to learn my speech down pat before the ceremony so I wouldn't spend the whole time looking down at piece of paper. My sister is such a musical prodigy that she can learn a song down pat after listening to it only once or twice.
