Unless the school states op10 n3 is unacceptable I wouldn't worry. Play what you like and are passionate about most, they want to see original creativity and potential for musical growth along with technical aptitude to handle demands of program . Saying the étude is not a fine choice is rubbish .I would suggest however learning two and listing both and letting them hear both or have them choose which they would like or perhaps they may have you play part of one in addition to a full other . When in doubt ASK THE SCHOOL-am
Do you really think that the fact that these are two of the most overplayed pieces in the piano repertoire doesn't count at all? In the end, we have to please the judges... And unless you play these pieces a lot better than the thousands of students that play them for the judges do, pick something else... expand your horizons! That also count when getting inside a school.
I would rather hear a zealous and enlivened performance of something the pianist is crazy about than a bland less common work even if I've heard the pianists choice more times than I care.The faculty panel are (at least they should be) functioning more as jury-judge with a assessment heavy on how good a fit the student is for the program, not as a competition judge.
