college rep and novices...

[Phantasmagoria]

I NOW REALIZE THIS SHOULD HAVE BEEN IN THE STUDENT FORUM, SORRY I WISH I COULD DELETE IT

I am not all that great of a pianist, by reading some of the people here, there are beginners of only a few months/1 year better then me, id probably say level five on the scale you use out of 8 (given that there are a few pieces of that I can play decently according to information on the site), ive had a few years of lessons but only recently (like in the past 6 months- year) have I been getting serious about it and also playing classical. I am 17 will soon be applying to colleges, though these will be lower tier state colleges,  not juillard and none of them even have official requirements (unlike some that are like, play a bach prelude and fugue, which I cant do unless its the first two) and I am not necessarily going to be a music major, but for some reason at least a few of them require auditions even for music minors which, so anyway:

I was wondering what the best course of action is as far is picking out pieces to play at my level.  The auditions for me are in December/January, so I have a bit of time to dedicate to learning two pieces, and I have never really done that.  I can play Mozart's Fantasy in Dm 397 well at speed except for the 32nd note parts which I cant play at the given tempo of presto.  I was thinking of using this as an audition piece, but I spoke with my piano teacher today and he said it would not be a good idea to slow these down to play it, as for an audition they would want it as written and would not be impressed.  So he picked out for me the well known Mozart Sonata No. 16 in C K545, movement one, and that I should do this other Chopin Marzuka (an easier one, number 14 I think) for the other selection.  I am wondering if this is a bad idea, since although I and he am confident I can play these pieces very well and precise for the audition (I already have the sonata movement's first 2 pages down after only looking at it a few times), would a piece as well known for being easy as the mozart sonata be a bad Idea?  also, any good ideas of songs at this level not particularily well known so there is less to judge, but appropirate for this environment?  I really am worried that both of these songs are not only too easy, but too over played.  my teacher might not know either, as he is not classically oriented


 As I said, it isnt like I am going to make a total fool of myself since these music departments have very little prestige, but it is still college, and I dont know if playing grade 5 pieces, especially well known ones, is a good idea or if I should strech myself with harder pieces?  I  yikes I wrote a lot thanks for reading if you did though!
