how can i learn to play this flute etude faster in 1 week or less?

i have regional auditions coming up. which is when all the band players from the region come and have to do a series of things for a contest. well the speed i’ve can play this etude on my metronome is 120 but the speed i need to play it is 198. every time i try to play it faster it sounds like i’m double tounging on each note. can someone please help me.
