Tips for learning a piece fast.

My teacher told me he wants me to play the "black keys etude" from chopin in exactly 2 months on an audition. My last two pieces were nocturne op 9 no.2 and Tempest sonata first movement.
I would try to learn the notes somehow in 4-6 weeks so I have at least two weeks left to make it sound good and fluent.

So, any advices? How could i learn it as fast as possible?
