The two posts above are excellent for your situation, IMHO!
Ah, Kölling!! This was a favorite of a number of teachers in my area as I was growing up. Great for technique building - finger work, scales, arpeggios - all in a piece that can sound quite effective. It is, however, still far below college audition level. When assigning pieces, most piano pedagogues are likely to include it in the Intermediate level like your Bach. The Chopin Waltz op. 64, no. 2 could possibly be categorized early advanced level.
The Revolutionary Etude is an incredible leap from your current level. It seems you think it will take about a year to learn? At the college level of instruction, it would be very rare for a piano major to be allowed to move that slowly. This is one of the challenges of college level study - majors are expected to traverse a wide range of literature at a brisk pace. With study for a double major, that could be quite a challenge if you aren’t already playing at a very advanced level with a deep repertoire base behind you. I have known students asked to leave their piano programs or to drop to Music Ed major if they can’t meet the progress expectations of the studio teacher. As noted in the above post, you are unlikely to encounter this level of demand if taking lessons as a science major. The instructor is much more likely to work within your abilities and time availability in setting expectations.
Your teacher may have sent students on to schools as piano majors. You might want to discuss where you stand as regards other students in the teacher’s experiences. If your teacher is not as familiar with current admissions environment as would be ideal, at some point you might want to check into scheduling an evaluation with a nearby university professor. This would be a private lesson with everyone understanding that you (and parents) need a “read” on your competitiveness for admission to different level schools.
